I think there is zero chance of SwanQueen. I mean how would that even work. Would that mean Emma is not able to have a good relationship with Snow because i just don’t see how it is possible for Regina and Snow to have a happy time relationship. I know i don’t want that to happen. Also it seems like Emma likes men from all that we have seen. Trying to kill someone does not usually equate to hey we are in love. I think that if it weren’t for the caveat that killing Emma would break the curse, Regina would have killed her already.
