I don’t think “Luke sneaking into his apprentice’s room” is a huge deal to start with. It’s his nephew, it’s not that creepy.
lolwat.
I’m not saying it’s normal, I’m just saying it’s not like he’s some random teacher, they’re family so it’s a lot less weird that they’d enter each other’s personal spaces without knocking. (I mean yeah there are things Luke could do that’d make the family connection be more creepy, but let’s not go there.)
It’s tough when there’s no real world analogue to what Luke does in there. I guess it’s kinda like if he went in at night to have a talk with his nephew about his potential psychopathy but first happened to see his journal by the door and opened it and found crazed ramblings about plans to kill everyone. Or something.
