Scenario one:
Mentally insane Blue
Extremely protective Razz

Branch off;
Razz finds Blue alone on the streets playing with a stick and some dirt, and every bone in his body was suddenly screaming at him to take the smol home with him. Turns out, Blue was actually an escapee from a not-so-good asylum.

And, if we're gonna do the branch off, then I want to be Blue since I have a lot planned for that one. If we don't do the branch off, then I don't mind at all.
