Having Hook really go after Emma whilst she’s in an emotionally vulnerable is a risky move depending on how they play it. If they do it where he acknowledges his feelings for her and wants to be there for her and help her and Emma realises how much support she has gotten from Hook WITHOUT him trying to push the romance front, then I have no issue with CaptainSwan. However if Hook is trying to push Emma into a romantic situation whilst she’s emotionally vulnerable, then that will be the final nail in CaptainSwan’s coffin.
I don’t hate CaptainSwan but I seem to go back and forth on it, same with SwanFire.
