Yellow Church is Caboose's mental image of Sister. Somehow he confused her for Church's twin brother who came from the moon. When Church killed himself inside Cabooses mind while using a grenade so he could get back out, Yellow Church was beside him and was forced out of Caboose's head alongside Church.

Yellow Church appeared beside one of the dead Wyomings and his time unit malfunctioned sending Yellow Church back to the point in Season 3 where there where dozens of Church copies. Thus giving us the Yellow Church we met in Season 3.
