I don't think it's that much of a deal, I'm ok with a little blood, it could be... other secretions... or tons of more blood with... much more horrifing... practices... YOU BETTER FUKING BELIEVE!!!! that I'll appreciate al lovely (incestish) picture of cute Elsa mestruating and cute Ana earning her red FUKING wings.... plus it's a vampire, it's justified, no deus ex machina here! :p
