Make Your Time

 is the fifth episode of the third season and the forty-third overall.

Synopsis
O'Malley activates Lopez's "secret weapon", a weather control device that Sarge had almost finished. The Red and Blue Teams join forces to confront O'Malley, who begins to wreak havoc with his rocket launcher. Simmons manages to teleport the Battle Creek grunts to Sidewinder and convinces them to attack and defeat O'Malley. Lightning from Lopez's weather device hits Church, thereby damaging the bomb in his body. When Sarge is subsequently unable to disable the bomb, Tucker tries to destroy Church with O'Malley's rocket launcher before Church explodes, but Wyoming snipes the launcher out of Tucker's hand. The bomb explodes and, due to the damage received from the lightning, destroys the present as well, sending both teams (except Church) to the future Halo 2. Donut attempts to direct a play to explain this sequence of events to Tucker. The group reasons that they were blown into the future because they were standing in front of Church; Tucker deduces that Church must have been blown into the past. Meanwhile, on a Marathon 2 map, Church appears, wondering what has happened.
