Character name/journal: Harry Potter || crux_ofmylife
Can he read your character's surface thoughts? Go for it! (Just remind me when he is 'cause... I suck at remembering)
Can he perceive your character's power level, and what would he detect? He's a wizard. he's fairly powerful. And, um, there's this little (spoiler for those who haven't read/seen yet) (/end) He's totally welcome to call Harry out on that. I'd say only privately, but I have no idea how well known that is these days. He doesn't talk about it publicly though, so he'll filter it if it's not.
