Hermione Jean Granger
Backtagging: Always and forever.
Threadhopping: If it makes sense, sure, but shooting me a PM wouldn't hurt. I'm usually pretty cool with that sort of thing (as long as the comment thread that doesn't involve Hermione doesn't get too long).
Fourthwalling: Anything from her future is off limits. I really don't think it would come up, but it would just make her pine. A pining Mione is no fun.
Offensive subjects (elaborate): None that I can think of at the moment?
Hugging this character: Hermione loves hugs and she will give them frequently to those close to her. Random stranger hugs may not go over as well, but hey - give it a try and dodge the Hexes.
Kissing this character: She will likely tense up and become very flustered if you are anyone but Ron. Again, Hexes might follow.
Flirting with this character: Go for it. It might be quite awkward, especially if your character comes on too strong.
Fighting with this character: Mione is always up for a duel thanks to the war. If you'd prefer a physical fight, well, she'd probably lose.
Injuring this character (include limits and severity): Let's talk about it beforehand.
Killing this character: Again, let's talk.
Using telepathy/mind reading abilities on this character: Shoot me a PM. I generally don't mind, but if it's something I want Hermione to keep secret, I'll either:
A.) Find a way to work around it ICly.
B.) Send you a PM asking that such and such not be brought up.
Power & Abilities: Hermione is a skilled witch. This covers her abilities/skills quite well.
Question: Can Hermione perform Magic on your character/characters?
