Simmons' Relationships

Simmons has developed multiple relationships with different characters throughout the series.

Red Team

It seems that Simmons shows the greatest concern and compassion to his team than everyone else. In a way, Simmons sees the Red team as his family; seeing Sarge as a father, Grif as a brother, and Donut as a "sister".

Sarge

Simmons has a great deal of respect for Sarge and seems to regard him as a father figure. As a result, Simmons frequently attempts to earn Sarge's approval by complimenting him in various ways. In the Blood Gulch Chronicles, despite sometimes being critical of his overly complex tactical decisions, Simmons always obeys Sarge's orders without question as he yearns to impress him. During Season 4, Sarge believed that Simmons had gone crazy and consequently demoted him, infuriating and upsetting him. Simmons joined the Blue team to exact his revenge on the Red team, showing how important being Sarge's right-hand-man meant to him. When Omega jumped into his armor in Season 5, Simmons disobeyed Sarge and threatened to kill him in order to become leader of the Red team, before saying that "From now on, everyone will kiss my ass!". This showed that Simmons was fed up with having to constantly kiss Sarge's ass, and after this he treats Sarge with far less reverence than before.

During the Recollections, Simmons is much less inclined to act professionally in front of Sarge. At the end of Reconstruction, when Sarge instructs Simmons to delete all information on the Blue team from Command's database, Simmons replies irritably when Sarge asks him to do something else, stating " Hey, I got a great idea, how 'bout if someone else does somethin' for once. I'm workin' here!". In Recreation, he becomes even less concerned about earning Sarge's respect, as he openly questions Sarge's decisions and is unenthusiastic about obeying his orders. Simmons then refuses to accompany Sarge, Grif, and Caboose in their mission to find Tucker and even appears to be eager for them to leave. However, Sarge does in fact respect Simmons, having stated that Command would've given him dozens of squads to lead in Revelation, while Simmons wants Sarge to call him "son" as shown in Recreation.

Grif

Grif and Simmons have a more complex relationship. The two spend a great amount of time together and are able to have decent conversations. However, the two are quick to bicker, insult one another in heated disputes, and also hated most of each others' qualities. After giving his organs to Grif, Simmons attempted to make Grif quit smoking and go on a healthy diet, but Simmons stated it was because he didn't want Grif's to ruin his organs like Grif did with his own. Simmons also revealed that he dreams about Grif's violent death, singing a jingle he never heard, and somehow waking up with an empty rifle in hands.

Despite this, Simmons does in fact value him as a friend as he jumped to save Grif and was sad when he believed he was dead. Simmons and Grif even have the same curiosity and ideas, as both usually agree about the military's actions and how to use the armor enhancements. Also when he joined the Blue team briefly, Grif tried to talk him back into the Reds, stating it wasn't the same without him and if Simmons did return he would treat him the same way before.

Donut

Simmons and Donut have a good relationship overall as the two are easily able to engage in decent conversations, although when Donut kept implying that Simmons was using drugs in Season 5, he clearly has Simmons annoyed. However, when Donut was crushed by the ship, he stated he would miss him like a sister. Simmons did show extreme concern when Donut was shot by Washington and panicked. After discovering that Donut was still alive in Three's a Crowd, Simmons seemed quite happy, but is shown to still hate his odd comments.

Lopez

Simmons talks to Lopez constantly, despite the fact that Lopez hates him, much to Lopez's annoyance although Lopez is willing to tolerate Simmons if he has to. He also seems to have a mild understanding of Lopez's language and was able to relate to Lopez by explaining he was part cyborg. Although his relationship with Lopez is odd and strained, Lopez's relationship with him is the best one Lopez has out of the Red team.

Blue Team

Simmons originally saw the Blues as enemies, shouting insults to them several times throughout the series. However, he has developed better relationships with each of them and has even joined the Blue Team on oncassions.

Church

Simmons and Church have little interaction during the course of the series. The time the two are able to interact properly is when Simmons temporarily sides with the Blues in which the two are able to engage in a decent conversation, although Church does boss him around and messes with his head at times. Later on, the two would work together to defeat the Meta in Reconstruction.

Epsilon

Simmons and Epsilon have a similar relationship that Simmons had with the original Church, but Epsilon seems to respect Simmons more. Simmons is hurt when Epsilon goes on an angry rant, blaming Simmons and the rest of the Reds and Blues for all of his problems in the past. Simmons does, however, decide to join the rest of the team to assist Epsilon and Carolina, deeming that they deserve a second chance.  It should be noted that his Epsilon-double was the only Red Team member to have his original personality at first.

Tucker

After being sent into the future, Simmons develops a relationship with Tucker that is similar to the one he has with Grif. Both seem to be able to work with each other to some extent when they're not fighting each other as well. In Season 10, Tucker disliked Simmons' driving, stating that he unwisely stopped the Warthog while they were under fire at a set of train tracks. It should be noted that despite having different personalities, Simmons and Tucker have several similarities as both are ranked Private First Class and harness exceptional combat skills. When he asks to stay with the Blues in Season 11, Tucker doesn't mind and the two seem to get along during this time.

Caboose

Originally, Simmons hated Caboose in Season 3, where Caboose was obtaining most of Sarge's attention. Simmons mainly now sees Caboose as an idiot and admits that he missed it when the Red Team only had to fight him in Recreation. Despite this, Simmons has helped Caboose several times and they see each other as good neighbors, or even friends, in some cases. This is shown in n+1, where he apologizes to Caboose on his "loss", and in Long Live the King, where Caboose states that Simmons can stay on Blue Team forever after being "elected" leader of the team.

Tex

Simmons has been shown to be fearful of Tex in most encounters they've had. However, he's been shown to have decent conversations with her, was willing to work with her to stop O'Malley, and help Epsilon-Tex access archived information in Revelation. Yet, he was willing to kill Epsilon-Tex in This One Goes to Eleven to stop her rampage.

Sheila

Simmons and Sheila seem to have a decent relationship with each other during their time together in Season 4. After Simmons was demoted for attempting to prove that the tank existed, under Sarge's false impression of him going crazy, Simmons joined the Blue Team and teamed up with Sheila to get payback. Sheila cheered him up, preventing him to commit suicide and was able to work with him.

Sister

When Sister originally came to Blood Gulch, Simmons was annoyed by her and thought she was unintelligent. However, after she reveals some of the things in her family, Simmons becomes very interested in her stories. While in the caverns beneath Blood Gulch, he was interested in seeing her naked which was shown on the large computer screen. Sister thinks that Simmons is a nerd and scary (which she thinks is "kinda hot").

Washington

Simmons first seemed to see Washington as a respectable and a more capable leader than Sarge; that is until Wash shoots Donut and Lopez in Recreation, as he yells at him furiously for his actions before Wash takes him as his prisoner in Revelation. However, Simmons seems to have mellowed out to Wash by Season 10. By then, he has given Wash a second chance and Wash, in turn, has shown to be friends with both the Reds and Blues, protecting them from Carolina when she threatened them. When Simmons joined the Blues in Season 11, Washington is exasperated by his actions before Simmons states he can call him "champ" or "son".

Freckles

When Caboose revealed Freckles in S.O.S., Simmons and Grif were terrified by the robot after it targeted them and later begged Sarge not to send him to spy on the Blues because of it. He was nearly shot by the Freckles in The Grass is Greener. The Blues are Bluer. before joining Blue Team and when Simmons tries to leave the team after Caboose was "elected" as leader, Freckles threatens him if he leaves and holds Simmons hostage.

Freelancers

Simmons sees most of the Freelancers as enemies responsible for several issues the teams had in the past. He even comes to the conclusion that "they are here" because of the Director (and Project Freelancer to an extent).

Wyoming

In the episode Uncommunicado, Simmons refers to Wyoming as a dick, after realizing that he has pinned down the Blues. When the Blues were fighting off the Wyoming clones, the Reds came to help them; Simmons killed several Wyomings using the machine gun turret and taunted them by calling them "cracker".

Meta

Simmons shows great fear of the Meta in the encounters they had and when he fights him. When the Meta appeared in Valhalla, Simmons made it his primary goal to escape the location with his teammates. In the final battle against the Meta at Sidewinder, Simmons was partially responsible for his demise, prevented him to kill Grif, and later described him as "the scariest fucking mute in the galaxy." Simmons is also the only character that faces him throughout the entirety of the Recollections.

Carolina

Simmons is concerned about Carolina, fearing that she may eliminate them once their mission is over or abandon them if they face mortal danger. When they return to Valhalla, Simmons immediately warns her about the possibility of an ambush from the UNSC, much to Carolina's confusion. At first he wasn't willing to aid her or Epsilon to kill the Director, however he, and the other Reds and Blues, eventually came to their rescue, believing that they should get a second chance much like Wash.

A.I.

Omega

Simmons sees O'Malley as nothing more than a common enemy for the Reds and Blues. At Sidewinder, Simmons lead the teams against Omega and was able to defeat him before the bomb went off. When O'Malley jumps into his armor, Simmons became disobedient and attempted to kill Sarge.

F.I.L.S.S.

It seems that Simmons' relationship with F.I.L.S.S. was similar to his relationship with Sheila. Both seem to get along to an extent, but when Simmons was restoring the data of the Blues, F.I.L.S.S. revealed that she could quickly restore them by using an archive database, humiliating Simmons. Noticing this, F.I.L.S.S. tried to comfort Simmons by telling him she could act like he hacked her to look good in front of his friends. After F.I.L.S.S. erases herself in Don't Say It, it's unknown if Simmons learns of and how he feels about it.

Others

Doc

Simmons seems to be very friendly with Doc, willing to have a conversation with him. Both even have similar traits as they both are quite intelligent. When Doc was first sent to Valhalla, Simmons said he was sorry to Doc for getting him involved and wished he wasn't the medic who was sent, suggesting he does care for Doc at some level. However, when Doc is trapped in the wall, Simmons abandons Doc when the Meta attacks, although he does attempt to free Doc first.

Vic Jr.

Simmons learned vital information from Vic Jr. before he returned to Red team and believed he betrayed the Reds. When Sarge contacted Vic Jr. in the caves, Simmons ultimately found Vic Jr. before he vanished, which may have hampered his plans and made Simmons realize that both teams were being used by him.

Andy

Although they haven't interacted much, Simmons shows a dislike for Andy, as the latter aided Omega when his group drugged Simmons and Grif for interrogation. However, Simmons was the one who suggested they use Andy to destroy the Pelican, much to Andy's joy.
