Leaving someone to take the fall for treason is pretty bad. Especially someone taking a risk to help you.

"Did you do something to set things right later? I mean, she lives here with you, and she seems to like you, so I'm assuming you did something to make up for that, right? And did her powers work to free your dad?"

Because Luca definitely wants confirmation that his dad came out okay...though he assumes he did since Varian says he wasn't freed right away, so he definitely was freed at some point.
