[OOC]
Backtagging: Yes, please! Seems like I always end up having to anyway... >.>
Threadhopping: Hmm. Let’s take it on a thread-by-thread basis - if you want to hop in, just ask.
Fourthwalling: Let's not with this one.
Offensive Subjects: None spring to mind!

[IC]
Hugging this character: Yes, go for it. She's from the South, casual, affectionate touch is no big deal for her.
Kissing this character: See above.
Flirting with this character: Oh, by all means! She'll almost certainly flirt back.
Relationships/Romance/Sexual with this character: Sex is a definite yes! Emotionally it's a little more difficult, because she does have a boy she's in love with at home, but at the point I'm pulling her from it's up in the air whether she'll ever be able to see her again. So an actual romantic relationship in-game... would probably take some work.

[Things That Could Affect Your Muses]
Part of Mona's power set is telepathy - she and her family read each other's minds as easily and casually as if they were just talking aloud. She obviously won't be using it that liberally in Eudio, but it is a thing she can do. Whether you're opting in or out of that, I'd really appreciate you dropping a line to let me know!

(Er, also, her narration is probably going to contain references to her sex life, which started when she was very very very underage, as well as incest/inbreeding - the Mayfair family tree doesn't fork. If you'd rather avoid those subjects/avoid Mona altogether, please let me know!)
