Leonardo has a nightmare that he has a bionic hand, which he cuts off fearing that it's part of Donatello's cyborg armor attempting to take over his body. The hand instantly grows into a pair ninja turtles that attack Leo, attempting to "assimilate" him. Leonardo wakes with a start as Don comes into the room. Leo tells his armored brother about the nightmare hand, and Don informs him that he was fitted with a bionic hand yesterday, which Leo gapes at.
