BOTH. and yes, i think that irregardless of her past with witches, kei would do her best to temper herself enough that she doesn't come across as super pushy and make things worse. but i can definitely see her having this desire to keep something like that from happening to lola again, especially if she considers them friends?
as for elisa, i'm laughing because kei's sister's name is elysa so that is perfect. but i haven't seen true blood in ages so i don't remember what bill is like in either season. BUT i love the idea of kei being friendly with a vampire. that plays completely into her uncontrollable urge to get herself into situations she shouldn't be in, and somehow surviving to tell the tale. how is elisa with witches and faeries since their blood is that magic sauce
