Threadjacking: You can do it. Do it until your heart's content.
Hugging (and/or shallow affection): Oh yeah, go for it. I don't mind and he may or may not mind.
Kissing (and/or intimate affection): Erm. Well. Er. Talk to or ask me prior to doing it. He's not really affectionate in this manner as far as I'm concerned.
Relationships: He's taken by Train, and owned by Eve. Lol, no really. I don't think he'll ever land a date no matter how self-styled he is.
Punching/Hurting (provided he can fight back): Absolutely. Depending on the circumstances, he will hit back.
Injuring: Of course, just be sure to plot with me ahead of time.
Killing: I'm an angst whore, so yes. Similar to above, I prefer to plot it out ahead of time.
Brainwash/Mind control/Etc: Again, absolutely. This may take serious plotting, but I'm all for causing havoc where it's not needed. 8Db
