The look Emma gives Killian though...
when it has to do with her past with her and Neal…
Always like she’s assumes Killian is going to run. That he’s going to abandon her like so many have before. She has a past and it’s one that causes her pain and now she cares about him and she’s afraid it’s going to scare him off. And so she always looks at him like this, for reassurance, to make sure that he’s not going to leave, and he never does. Because he loves everything that she is, scars and all.
