i. He's had no formal training, but there's a good number of ah, repressed memories? Things he tries to forget. And he does most of his thinking/remembering in Italian anyway...

ii. He's fairly resilient-- his genetics have kept him from being controlled before, but I wouldn't be surprised if he has to struggle a little bit first.

iii. Coma it is!

iv. It might really hurt his eyes? Other than that, probably not.

v. Sorta? He's almost magically sneaky and stealthy and is really good at finding people, even if he's never seen them before, or even if they're disguised. His Eagle Vision probably won't ping magical or muggle, but uh. Yeah.
