Aftermath, Before Biology - S2.E16

Disoriented from the events of the previous episode, Doc discovers a hovercraft in a cave and consults with Vic, who proves to be unhelpful. Meanwhile, Tex has disappeared, and Grif awakes from surgery to find that Sarge has replaced most of his organs, which had been damaged in the accident with Sheila, with those left over from Simmons' cyborg operation.
