2x11 - Red vs. Blue

The Blues convince Lopez to repair Sheila. As he works, Grif spies him through a sniper rifle and assumes that there is a "new" Blue soldier. The Red Team discusses various explanations. Donut manages to guess the truth, but no one believes him. Once Lopez finishes repairs, he and Sheila fall in love with each other, much to Caboose's dismay. To disrupt the odd love triangle, Church attempts to possess Lopez again, but is unsuccessful; instead, it is Tex who suddenly appears in Lopez's body.
