Once Upon a Time: Hook Is Ready to Confront Emma About Her Secret

There's trouble in paradise on Once Upon a Timefor Captain Hook (Colin O'Donoghue) and Emma (Jennifer Morrison) now that Emma is keeping a major secret from her love.

In last Sunday's season premiere, Emma began getting visions of her own death and found out at the end of the episode they are visions of the future and there's nothing she can do to stop her death from coming. That sounds like something you should tell your boyfriend who you just went to the underworld to save, right? Apparently, that's not how this is going to go down.

TVGuide.com caught up with O'Donoghue to talk about how Hook feels about the secret, this juncture in the "Captain Swan" relationship and what else is in store for Storybrooke's swashbuckling hero.

Emma is keeping this huge secret from Hook. Does he believe her when she says everything is fine or is he suspicious at all?

Colin O'Donoghue: Oh he doesn't believe her. He definitely knows that something is not right. We saw in the premiere episode that she's quite short with him and says to go and she's never like that with Hook. They're honest with each other. I think he knows something is up and he'll try and figure out a way to get that out of her and find out what that is.

How long is it going to take him to confront her about it?

O'Donoghue: [Laughs] Not too long! We see that he'll approach it and see what's going on with her. I think if he does find out the truth that she's hiding something ... he'll be mad with her but he loves her so he'll do whatever he can to help her, you know?

Once Upon a Time: Is Emma marked for death?

Well, is he going to confront her directly about it or is he going to come up with a long-term game plan to softly approach her about it? Or will he figure it out on his own?

O'Donoghue: He's able to confront her about it. He's never been shy about confronting [her] and saying "I know you're holding something from me and you need to tell me what it is." I think he has no problem doing that.

And how well is that going to go?

O'Donoghue: [Laughs] Well, I guess you'll have to watch to find out! But look, they love each other and they don't really want to have any secrets. They've said that in the past. Emma has said whatever Hook has done in his past life she's willing to let that go because of who he is now, and he knows that she knows all of these terrible secrets about him so they really don't keep things from each other anymore. That's why it's so strange why he would not tell him the truth on this.

Would you say he feels betrayed or do you think there's a part that understands or thinks "there has to be a good reason why she's keeping this from me?"

O'Donoghue: I think it depends. ... If he found out he might feel a bit betrayed, but that's if he finds out.

Assuming that he finds out eventually, how would he react to the truth?

O'Donoghue: I think he would be disappointed that she didn't feel confident enough in him to trust him with the knowledge of her visions or whatever.

And they've gone back and forth a lot over the years. Do you think he also sees this is as a step backwards, like a regression almost? Last year she said "I love you" to him.

O'Donoghue: He knows that she loves him and that they have a good relationship, but I think ... maybe not a step back. I just think he would be disappointed she wouldn't trust him enough to tell him and figure out a way to combat it together as opposed to her dealing with all that on her own.

If you were their couples counselor what would you recommend they do to get over their communication issues?

O'Donoghue: I don't think I can say that [laughs]. I would say that they need to be more honest and open with each other and trust that the other person has their back.

On Sunday's episode Hook is going to help Belle hide from Mr. Gold. How is that going to work out? This is the second time Hook has come between Gold and and the woman he loves.

O'Donoghue: In this situation Hook helps Belle because she wants help. She doesn't want to have Gold in her life anymore and at the moment she doesn't want Gold in their son's life. ... Hook is helping her because that's the right thing to do in that moment. The fact that it's getting one up on Rumple doesn't hurt as well. But he's happy to help her and wants to do whatever he can sort of make amends for how he treated her in the past. So we get to see a little bit of that. And also, she wants to be hidden and who better to hide anything than a pirate?

So he doesn't have any ulterior motives, like he actually wants to help Belle?

O'Donoghue: He wants to help her, yeah. Hook now is trying to be the best person that he can be and be the hero that everybody agrees that he can be. That's why he's helping her.

Once Upon a Time EPs answers to all your burning premiere questions

Captain Nemo is showing up later this season, and we know he has some sort of history with Hook. What can you tease about that?

O'Donoghue: I can't tease a huge amount other than exactly what you just said. But he does show up, and you see he has a past [with Hook]. I'm pretty certain when it was announced that Captain Nemo was going to be [in this season] that everybody would assume he had some sort of past with Hook. It's fascinating. And Faran Tahir, who played Nemo, is just phenomenal. So it was great to get to play with him, but it's a really interesting story and it's a really good take on Nemo and the whole Twenty Thousand Leagues Under the Sea world. And yeah, it was very, very exciting to do that.

Can you describe Hook's reaction to seeing him at least?

O'Donoghue: Surprised, I guess? [chuckles] That's about all you're going to get!
