Hey, if she'd rather stay home, not get involved and go on and live a happy little life and grow up to follow her dreams without ever having to spare a thought for what allows her to do that... he'll go ahead and tell her to do that too.

What he might do is hit her with a big reality check if she starts treating jumping around with superpowers and playing hero like a game. Go home or go all-in but don't get in the way and all.
