The Missing Mistletoe - Swanqueen

Regina and Emma had feelings for each other, the tension could be perceived from a thousand miles away. Everyone seemed to know that. Well, everyone except them. Henry had a plan, and he was aware that unless he intervened, Emma and Regina would never make a move on each other. One would say that it was way too dramatic, however, drastic measures had to be taken in order to succeed. If his moms found out, he would be in serious trouble, that is, unless his plan works as intended.
Set some time after Emma becomes the Dark One.
