Epsilon's storage unit suddenly opens up, and the figure of Delta is seen. He explains that Epsilon chose this form because Delta was the main source of information from Caboose's stories. Delta asks Caboose for his help on a mission; specifically, he asks Caboose to take him to the source of energy that Donut had previously mentioned, and also where Tucker is supposed to be, so they can punish those who harmed Alpha. Delta states that they must find it themselves because Washington doesn't trust Epsilon and Caboose constantly fails at building a new body for Epsilon, explicitly remembering the fires. Caboose agrees to go on this mission. As Delta disappears, the Reds arrive and Caboose tells them that he is leaving to get Tucker. Grif volunteers to go with him so that he can ensure Command acknowledges the Blues exist. Sarge decides to go as well, but Simmons chooses to stay behind with Donut and offer 'logistical support'.
