Really, I have no idea; but I'd like to believe that he will :)

He will because he's trying to prove to everyone that he is a good man, a man of honour. It won't be easy for him, but he'll do it! I have no doubt about it!

I think so

This is an interesting problem he has here.

On one hand, Hook cares for both Emma and Bae. He sees Milah in Bae, and I think wants to protect Bae if he can. He also loves Emma and might think she deserves to know.

On the other hand, he could not tell them for various reasons. He could revert back to his selfish ways and not tell her because he wants her for himself. Or he might choose not to tell them because if Emma knew Pan came to see him, who knows how she would react.

Or they could encounter Neal before he even gets the chance to tell Emma. Lots of possibilities!

Emma finds out he Is alive so he must.

I think he will, but I'm not completely sure.

Lots of possibilities indeed @misse1000!
He really should but maybe he is too late in the end.

I sure hope he tells her! I hate dishonesty and lies and I don't want his character to get ruined for me. This is the kind of information that just mustn't keep from her. She has the right to know.

I dont know, but something tells me he wont.
