Yeah, Regina would have made more sense, too.
Hook has relationships with everyone, but only his relationship with Emma is one that anyone would go to the underworld to save him for. What we’ve been shown on screen is Henry’s having mixed feelings about Emma dating Hook but enjoying Hook’s lessons in piracy, Regina having a normal covillain animosity toward Hook, Robin having…done stuff with Hook cuz he was there, the Charmings tolerating Hook for Emma’s sake, and Gold loathing Hook passionately with the feeling entirely mutual. Belle actually became friends with Hook while they were working to free the fairies, but when they decided to make her almost entirely OOC for the last three eps of 5A, they kinda dropped the friendship, too. None of them save Emma has a truly positive connection to Hook and half don’t really have a relationship that’s been developed on screen. Which is actually strange considering Hook has one of the highest screentimes out of the regulars.
