That... has a lot of information that's completely unfamiliar to him, and despite his interest, Phineas doesn't chase most of it up. It's probably not a great idea to ask approximately a dozen questions of someone else who's been dragged here unwillingly right out of the gate.

What he does ask, though, is, "So you're capable of transformation... You're an android, right?" Just checking, but she really seems to be one and he can't keep from asking that particular question any longer.
