(I'm pretending to know a lot about LJ roleplaying and fleshing out this account with information other people in United One are kindly providing.)
Battling/Trading: Definitely! Thomas is going to love battling.
Plotting: Love to. Let me know! I'll probably do any kind of plot, haha.
Flirting: Oh, sure. Thomas has very Victorian sensibilities, though. Even if he does push the boundaries of those limits in his own time on occasion, he is extremely old-fashioned for modern times. Flirting might be awkward.
Hugging: He is not at all used to hugging, but I'm not going to say you can't do it, haha.
Kissing: Well...! I mean, I give you permission to try.
Injuring/Killing/Fighting: Yep! Thomas will fight back, though, (he's got a gun!) and I'd rather you didn't kill him. Then I wouldn't have a character, haha. But yes, injure away.
Mind reading: If you can read minds WHO AM I TO STOP YOU
Manipulating: Yup.
Backtagging: I don't know what this is. Probably? CONTEXT CLUES YOU HAVE FAILED ME Yep, go ahead.
Anything else: Probably!
