The prince married Snow White and made her his queen. I would like to say they lived happily ever after but having lived around her for some time I have my doubts that all went smoothly.

As for the old Queen, some say Snow White invited her to a party and the old lady never left alive.

Others think Queen had made enemies of the other witches so one of them may have done her in. Myself, I like to think she tried to summon the nature spirits and make them do her evil work but those were the ones that were friendly with Snow White and they made sure that the Queen could never hurt her again.
