"Once Upon A Time" season 4 spoilers reveal that Captain Hook might have to change his outdated pirate-y look, as "Frozen" characters won't be related to anybody from Storybrooke.

Colin O'Donoghue (Captain Hook) dished out "Once Upon A Time" season 4 spoilers during the recent Comic-Con when he said that his character might get out of his pirate clothes when the show resumes, but did not provide any more details.

In a recent interview with IGN , he was asked to describe what his new costume would be like.

"Yeah. I cant really talk too much about it, but he'll have a change. He'll be in slightly more modern clothes. That's about as much as I'm allowed to say," he said.

Captain Hook wearing "modern clothes" in lieu of his pirate costume could happen when he goes on official date with Emma Swan.

Earlier, producer Edward Kitsis earlier revealed "Once Upon A Time" season 4 spoilers to E! News when he said that Emma Swan and Captain Hook will go on a romantic date.

"If you notice, they haven't had a proper date. Their dates have been running from time travels and portals and monsters, so they're going to have a proper date," the showrunner said.

Meanwhile, creator Adam Horowitz dished out "Once Upon A Time" season 4 spoilers to TVLine when he said that they won't necessarily complicate the characters of "Frozen" when they are introduced into Storybrooke.

Speculations have circulated that some of the "Frozen" characters might be related to some people on Storybrooke. The rumors have been triggered by the big reveals on season 3 where Peter Pan is actually Rumplestiltskin father and Regina is half-sister to the Wicked Witch.

"We will go on record as saying that we are not going to reveal that, for example, Elsa is somebody's sister," Horowitz said.
