My hope for Hook now is that the writers don’t try and push the CS stuff too early after Neal’s death. Let Hook be there for Emma, let him support her and comfort her if needed, but don’t make him look like he is trying to come on to Emma whilst she is still emotionally vulnerable after Neal’s death.
I think Hook will be as he’s always been with Emma since the kiss in Good Form, which is respectful of her wishes. I don’t foresee that changing and him going back to the old version of himself. Besides, Nealfire was someone both he and Emma knew. Of course, Hook will be there for Emma as a friend (that’s to be expected, I think) but I don’t think he’ll push her into anything she’s not ready for. That would be very Out of Character at this point for him.
