OUT OF CHARACTER
THREADHOPPING check with me first. generally, it's fine, but just in case.
FOURTH-WALLING no for once upon a time, yes for beauty and the beast.
OFFENSIVE SUBJECT none in particular; if you're worried about something (and this is my policy in general), just hit me up and we'll talk about it!
KISSING you can try. she'll get weird.
FLIRTING go for it. again - she'll get weird.
FIGHTING arguing, yes. physicality, check with me (it will probably be yes).
INJURING check with me.
KILLING check with me.
TELEPATHY, ETC. yes - but you might want to just let me know what's up so i can give you hints in my tags!
