Alright, Oncers -- listen carefully! Remember in the past when we've advised you to keep an inhaler by your side before you read one of our Captain Swan-themed articles? This is one of those breath-taking times.

We just got off the phone with Once Upon a Time star Colin O'Donoghue and asked him everything your Hook-loving hearts have wanted to know about season six. What's up with Killian's past? Where is Hook currently living? Is he so excited that his BFF, Sean Maguire, is going to be returning as Robin Hood?

We've got all of those answers (plus many more!) jam-packed into the article below and we're challenging you to see how many times you can re-read his responses before this Sunday's all-new episode.

Oh! And did we mention we asked O'Donoghue to plan Emma and Killian's ultimate proposal? Enjoy…

ET: What was your reaction when you found out that Emma would, once again, be hiding her secrets from Killian?
Colin O'Donoghue:
Yeah, it was a bit mean of her not to tell him what's going on, but I think for Hook, he he'll do whatever he can to help Emma and he believes that they have a relationship where they can be honest and open with each other. I think that he knows that something is not right, and that she's hiding something and, at this point, there's something that she won't share.

How long are we going to have to wait until Killian really finds out what's going on?
I think that he'll approach the subject with her pretty much straight away. I mean, he's not shy with approaching her and tackling things, so I think that he'll say something pretty soon.

We have seen Killian go to hell and back -- literally! -- in season five. What's next for him in season six?
He's trying to be the best person that he can be, and be the hero that everyone believes that he can be. He also wants to be the best man for Emma, so whatever he can to do to prove to her that he's worthy of her love, that's where he is at the start of this season. You'll see him in this next episode where he helps Belle and he's doing it simply because he wants to just help. He wants to try and make amends for some of his past actions, with Belle and just in general. He knows that he has done wrong by people and he wants to make amends for all that.

We got a little bit deeper into Killian's past last season and learned even more about his brother, Liam. Will we be diving even deeper into what makes Killian tick this year?
Yeah, we'll definitely see a little bit more of Hook's past. I can't really talk about it just at the minute, but we'll see some of the relationships that he had in his past, and sort of a little bit more about his whole family life. I mean, Hook is hundreds of years old, so there's a lot of stuff to get through, but it's always fun to play old Hook and sort of explore what he was like hundreds of years ago. We'll definitely see more of his past.

We've always seen a really fun and interesting dynamic between old Hook and the original Evil Queen. With The Evil Queen coming back into the picture, are we going to see any fun scenes between her and Hook?
Yeah, you'll definitely see some scenes with Hook and The Evil Queen. I mean, Hook definitely is a different person now then he was back then. I don't even know what kind of a relationship he and The Evil Queen had back then! [Laughs] But he's a different man now, and I think he definitely wants to try and figure out a way of stopping The Evil Queen from achieving whatever she's trying to achieve. She's now The Evil Queen without any of Regina in her -- that part that would've maybe questioned things in the past. Now she's just pure evil. She's the Mr. Hyde of that relationship.

One of your best friends, Sean Maguire -- who we've missed desperately as Robin Hood -- is coming back to the show for a bit. What was your reaction when you found out that Robin isn't completely gone for good?
Wait. Who said best friends? I never said that. Did he say that? [Laughs] No, I'm very excited. It's great to have him back up. I literally know nothing abut the context of the story, or how that's going to work, but it'll l just be great to have Sean back for a little while. He's just a great guy, but don’t tell him I said that. It'll be fun, we'll have fun times.

A lot of fans have expressed that they'd really like to see Killian bond more with the Charming family, especially with Henry. Is that something that they can look forward to?
Yeah, you know, Hook is now a part of Emma's life and, obviously, they're Emma's family, so you'll definitely see a lot more of his interactions with both Henry and also Charming. I can't really go into too much detail, but definitely with Charming we'll see a big development in their relationship further on down the line. And Henry is a teenage boy and, I guess, Hook is, in some way, a father figure -- or trying to be a father figure -- for him, so that's kind of where they're at. Hook is trying to do his best by them all, but he still has a pretty dark past.

Are we going to be seeing where Killian will be living this year? He's kind of been all over the place -- he was on the Jolly Roger, he was in Granny's, etc. Has he officially moved in with Emma yet?
He hasn't officially moved in at this point where we are, but he picked out the house, so he really should be there. I'm not even sure in the next episode on Sunday exactly where he lives. I don’t know if he's on the Jolly Roger, or if he's at Granny's, or where he is. I think he's just kind of floating around at the minute. Hopefully, soon he will find a place to live. Hopefully.

Hopefully with Emma because, you're right, I totally forgot that he picked out her house!
Yeah, he's got good taste!

Alright, Colin, when I caught up with you [at Comic Con] I asked if season six is going to be the year that either Killian or Emma pop the question to the other. How would you plan their perfect proposal?
[Laughs] I wouldn’t have a clue! Maybe some rum on the Jolly Roger? A candlelit dinner with grilled cheese and French fries, and a nice vintage rum, and I guess that would probably be it.

Do you think it would be Emma or Hook doing the proposing?
I don't know if he would be the one to pop the question or not. That's a pretty big step. I think that they're navigating having a relationship in a town where they've got so many evil people trying to kill everybody! [Laughs] I don't know if they have time, really, to think about popping the question.

Once Upon a Time airs Sundays at 8 p.m. ET/PT on ABC.
