Have We Met?

 is the fourteenth episode of the third season and the fifty-second overall.

Synopsis
Future-Church watches past Tex, Donut, and Tucker leave Blood Gulch for Sidewinder. Future-Church whispers a plan to Sheila, and then follows the others, leaving Sheila alone in Blood Gulch for the better part of a millennium. At Sidewinder, future-Church frees past Church and Grif from their cell and then attempts to stop the bomb from going off. He fails repeatedly, which results in his being tossed back in time to Gary's terminal. The flock of Churches begin to convene at Sidewinder to discuss past failures and come up with new plans to fix their mistakes. The final Church, however, gives up on fixing the past. He simply walks up to the Blood Gulch gang and gets blown into the future with them. Popping into existence just outside O'Malley's fortress, he gets Gary to unlock the doors and shut off the bomb, and everyone is saved.
