Jennifer Morrison has a dream for where she wants to see our heroes on ABC's Once Upon a Time end up next.

As Emma (Morrison) and the gang try to escape the Underworld, there is some speculation as to where the show may go in the future. Morrison has a particular hope that may not come to pass but remains a cool idea:

"I think my fantasy for the show will probably never happen. I'd love to do, I don't know, rock and roll in the '60s," Morrison told E! News recently. "I don't think that's in the cards for us."

But the gang can't bother to worry about that right now, considering they're just trying to get out of the Underworld, which is proving to be much more difficult than once thought. Morrison spoke on this realization among our heroes that this is going to be a rough one.

"We knew it would be difficult to get home no matter what, but now that we have extra obstacles in the way, there's multiple things stopping us, now, from getting back," Morrison said. "So it's not going to be a direct route, [but] a more complicated plan to actually get us all out of there."

For the time being, Emma will try to free Hook (Colin O'Donoghue) by plunging even further into the Underworld.

"Nothing is as easy as it sounds," Morrison teased, when asked about her upcoming journey. "Not that going to the most dangerous place in hell sounds easy, but I guess the adventure is always different than you expect, right?"

Morrison also discussed how Emma's relationship with Hook will evolve assuming they are able to successfully escape the Underworld.

"I think it's interesting now that we're looking at the relationship as a real relationship and the ups and downs that's in a real relationship, and the intimacy that you discover when you know that you've decided that that's the person you want to be with," she said. "I think that's definitely stuff that we're looking to start exploring between Hook and Emma."

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