T-Rex: It's the future, and Future T-Rex (henceforth, "T-Rex") has uploaded his brain to a computer! Of course, this is a non-destructive process, so now T-Rex can chat with Computer Brain T-Rex (henceforth, "Cyber-Rex 2000").

T-Rex: Thus begins the comedy of T-Rex and Cyber-Rex 2000!

T-Rex: Initially things are good, but as time goes on T-Rex keeps asking Cyber-Rex 2000 to keep track of his appointments, and how much 2 cups of butter weighs, and so on. "I'm not a digital assistant," says Cyber-Rex 2000, "I'm you. Only I'm in a computer."
T-Rex: "Seems like a computer me would be willing to look up how much 2 cups of butter weighs", says T-Rex.

Utahraptor: This leads to a schism between the two?
T-Rex: Boy, does it!

T-Rex: Cyber-Rex 2000 wants to kill T-Rex AND knows him literally as well as he knows himself. This makes it very hard for T-Rex to hide, especially since everyone else is saying "Wow, MY brain upload didn't get murderous on purpose, this is making me re-evaluate everything I thought I knew about you."

T-Rex: That said, there's very little Cyber-Rex 2000 can do, because in the future all software is properly sandboxed. THE END.
Off panel: ...What?
T-Rex: SOFTWARE SECURITY IS NO JOKE
