Red vs. Blue - Season 5 - Eps 21: Same Old, Same Old
Caboose deduces that he must leave Sheila to help his teammates at Red base. Meanwhile, Tucker finds out that Wyoming has the ability to loop time, having gained it from the AI implantation process, just like Tex's camouflage and York's regeneration. By rewinding events until he is victorious in battle, Wyoming is able to detect the invisible Tex before she attacks and kill Caboose. Tucker uses his knowledge of the loop to impale Wyoming with the sword, and save his teammates. When told of the loop, Church wonders if copies of Wyoming were made, as they were when he time-traveled, when the two come across multiple Wyomings.
