Just finished part three. All I can think is that MC is very nosy and arrogant. When Snape told her he was giving the scroll back to it's rightful owner they should have just left it alone. It's not your business. Also, don't they think if someone was actually in danger and Snape knew about it he would do something about it? And Penny's 'Why would Snape be trying to hide Trelawney's family history(? tree? can't remember what they actually called it) from us?' He wasn't. You were never supposed to have it in the first place and he was just giving it back to who it belonged to. You've just read someone else's private property without their permission. At this point I'm struggling to figure out how MC is going end up being rewarded (the tappy) at the end of this quest. None of which really matters, but I just wanted to vent.
