Ivan

[OOC]

Backtagging: Absolutely. I will backtag into infinity.
Threadhopping: Yes, provided anyone else involved is fine with it and it isn't something private.
Fourthwalling: Depends on the circumstances. Ask first.
Offensive subjects: None. I won't RP smut with him, though.

[IC]

Hugging this character: Yes.
Kissing this character: You can try. He'll be very flustered.
Flirting with this character: See above.
Fighting with this character: Yes. So much yes.
Injuring this character: Probably. Get in touch with me and we'll work it out.
Killing this character: Probably not... but never say never. If you have something specific in mind, hit me up.
Using telepathy/mind reading abilities on this character: Yes, but he's a mind reader himself, so be warned--two can play at that game!

Warnings: As mentioned above, Ivan has the ability to read people's thoughts, and can acquire a lot of information about someone after only a few moments of rooting around in their brain. He has to be quite physically close to the person for it to work (actual contact helps), and it's something he has to make a conscious choice to do; it doesn't just happen. Characters with magical/supernatural abilities might be able to tell when he's using this power on them, and I'll be sure to clear any major mind reading beforehand.

He can also see through illusions, but again, it's a power he has to choose to use rather than one that's always active.
