explain what real danger hunter would put the girls in, that sterling's only choice is to kill hunter first?
as far as we all know, hunter doesn't physically hurt nor want to kill any one in his family. what he does to them is disgusting, but sterling wants the same things too. he wants to have sex with the girls, but not through underhanded methods. so i don't think sterling will kill hunter because hunter has sex with the girls. this is a tricky situation, because we know he can do it in non-canon, but we can't see him do it in canon because that would mean a hunter sex scene in canon. anything can be used in a bad end, because it's not what really happens.
nothing is certain, but more likely april to may. it's only just over half done so to be able to finish up in march isn't realistic.
