Fourthwalling: In my character's universe, Tron was a bestselling video game and possibly movie. Knowing Alan as the model for Tron's face is fine, but please don't fourthwall otherwise.
Touching, hugging, flirting, kissing... : Feel free to do any of these, but Alan will under most circumstances politely inform people that he's married. (He'd rather manipulate people's minds than use physical persuasion.)
Fighting, Injury, Killing: Fighting and injury is okay, though please bear in mind that he's a sixty-year-old human and not used to actually fighting. I'd rather not have him killed off except for a very good reason (though it has happened in the past). For any of the above, ask me and we'll discuss it.
Anything specific for this character? Alan has very few morals, and is a manipulative bastard. If I make you uncomfortable, please contact me and we can sort things out.
