"Well hello mister fancy-pants. Forgive me if I don't shake hands."
The Ancient One attempts to play some mind-games on Caleb by possessing the original (now dead) bodies of the other three Chosen. It backfires.
Caleb: Aww, you're gonna hurt my feelings.
He also tries to deliver a dramatic villain speech about undoing all reality, and retroactively eliminating the past, only to realize he has no idea what's supposed to happen to the future. Caleb patiently lets him finish hesitating, even egging him on with an impatient "Well?".
Leaving Caleb idle for long enough, Caleb starts to sing snippets of several music works, including "I did it myy waaaaaaayy...", and parodies of afew others. Amusingly, he can do this after he's killed.
