This is what I love about OUAT. Belle comes looking for help, she tells Emma and Killian that she’s estranged from her husband, and a few things happen. Emma deems that Granny’s is not good enough, she wants to do better for her friend. But she can’t go right now. So Killian and Belle go alone. And there’s not a hint of worry or jealousy or any of the silly drama that you’d get in some other shows when the main character’s boyfriend goes off alone with a newly-single friend.
Emma wants better for Belle, and doesn’t bat an eyelid at the idea of Killian helping her find that. Because this is a real relationship and real friendship and there’s trust and yeah. I just love that.
