My personal theory with this episode is that it will be detailing what Hook is up to after Emma's to-be-revealed mysterious disappearance. I'd assume JMo's episode, the premiere, is going to detail what happened to Emma, but Colin is staying on the show which means we're gonna have Hook sans-Emma to deal with. This episode will probably show how he's dealing with Emma being gone.

My reasoning is this:

Remember back in S3 when all the EF people went back to the EF when Regina stopped Pan's curse, except Henry and Emma because Emma had to take care of Henry? Well, this was right around the time when Hook was falling for Emma. When he was returned to the EF without her, he tried really hard to go back to being a pirate and forget about her- but he couldn't. He ended up trading the Jolly Roger for a bean to get the memory potion to Emma, proving that he was no longer who he used to be. Now, if I recall correctly, there's a scene where Hook is talking with Emma, Mary Margaret, and David about what went down in the missing year, and he's explaining how he didn't get caught up in the curse because he left the group. I believe the quote was, "I had a life to get back to. A pirate's life." (Helpful bolding included for emphasis)

Now that doesn't sound familiar at all, does it?

So imo this ep should be him dealing with Emma being gone. Probably trying to put her behind him and failing miserably or something.
