It is just so out of character. I always thought that Emma would just get married just in her street clothes like Snow and Charming did in the forest with just Lancelot and his mom there. Obviously Emma marrying Hook is out of character as well, but the way the wedding is also out of character. It seems out of character for Snow too who seems to be coming up with these ideas. I mean think of Snow’s wedding dress from their second wedding. It is a mess all around.
