I've just seen the sneak peeks, and I noticed something that would make CS fans very happy.
In the scene where Emma and Rumple are looking for Bealfire/Neal, and Emma speaks into the speaker, Neal recognises her voice so he runs. He doesn't know that Rumple is with Emma, so therefore he is still running away from her. However in contrast to Hook – Hook stays and fights for what he wants 'A man unwilling to fight for what he wants, deserves what he gets'. I truly believe that this famous quote will come up again, and this time will be directed at Neal/Bealfire.
Also, while I'm on this topic, Neal got a postcard at the start of the season and he still hasn't gone to find Emma.
So in my eyes, I can already tell who is more suited to Emma – Captain Hook. I find them both so alike and so perfect for each other.
As for Neal I believe that he will find someone else who he will be willing to fight for, because right now his not even lifting a finger for Emma.
