Emma: Gryffindor, as obvious as this one may have been, it was between this and Slytherin which doesn't suit as well
Killian: Ravenclaw, this man uses words such as "moniker" on the daily, and people usually die or get into trouble when they dont heed his warnings
Rumple: Slytherin, I wanted to be less predictions but where else would he go?
Belle: Ravenclaw, she's the one that helps them reasearch things to defeat the latest bad guy
Regina: Slytherin, not because of her evil but for her personality. Her determination, her strive to her goal, and other Slytherin properties (cant forget the sass👌)
David and Snow: Gryffindor, I'm trying to he less predictable but its perfect!
Robin: Hufflepuff, it just works
Henry: Ravenclaw, he's incredibly smart if we're being honest! And it suits better than most houses
Neal/Baelfire: Hufflepuff, he just is
Zelena: Slytherin, it even matches her color scheme
