User blog comment:Western Gen/Speculations for Season 13/@comment-115.133.123.112-20150526070420

I noticed a pattern of some sort. Could be coincidence but here it is. You know how it was mentioned that Season 11 was BGC, 12 being Recollections and 13, Freelancer saga.

In BGC, the Great Prophecy plot began in Season 3 which was also the season when Tucker found a Sangheili energy sword, revealed to be the Great Weapon. Other than been used for swish, swish, stab, it also has other features such as unlocking secret vaults or something. That part was from Season 4. In Season 13 episode 4, Tucker unlocked the temple.

Next in Recollections, After Reconstruction, Caboose was trying to revive Church but with no results. Caboose finally succeeded in Recreation when he installed Epsilon into a Forerunner Monitor. Then came Season 13, episode 8 where Caboose returned with the Alien AI, Santa.

Another interesting note, the first episode of Season 13 was called "Prologue". In my opinion, prologue would be like Episode 0. Thinking like that, Episode 4 "Tourist Traps" and Episode 8 "Test Your Might" would be Episode 3 and 7. That's right folks, 3 and 7. The same numbers with Season 3 and 7.
