Once Upon A Time Season 4, Episode 2, titled "White Out," airs Sunday, Oct. 5 on ABC. In this episode, viewers learn of an Arendelle-Enchanted Forest connection through Anna and Prince Charming. Read on for more spoilers.

Spoiler alert: This feature contains spoilers on Once Upon A Time Season 4. Watch the season premiere on ABC Go to stay updated. This week's new episode is the second installment of the "Frozen" arc.

On TV.com, the OUAT 4x2 synopsis reads:

"Ella accidentally endangers Emma's life when her ice powers go out of control again. Meanwhile, when Regina goes into seclusion, Mary Margaret takes charge of the town and faces her first crisis. In the past, Anna meets David and helps him learn to fight for what is his against a brutal warlord... the dreaded Bo Peep."

"We're going to go back even before what we've seen previously of David, when he was a shepherd," Josh Dallas (who plays David/Prince Charming) told TVGuide, hinting that viewers would find his flashback hairstyle quite amusing.

"When the wind hit me, it blew, like I was Beyonce or something," Dallas told TVGuide.

Bo Peep is in Disney's "Toy Story" as a ceramic doll and Woody's girlfriend. "Little Bo Peep" was originally popularized as a nursery rhyme.

In the same report, Dallas said David - before he was Prince Charming - "has another connection to someone else in Arendelle." It remains to be seen whether this connection is revealed in Once Upon A Time Season 4, Episode 2.

Robin Weigert ("Deadwood") is playing Bo Peep in OUAT 4x02. ABC allows its viewers to watch previously aired episodes on ABC Go. Fans who missed the premiere run on Sunday could catch up on the network's Go website.

Delving further into the spoilers, Dallas shares with TV Guide Anna's role in her life, and how Bo Peep was instrumental to David's courage.

"Anna really teaches [David] to face life and stop running from things. His instinct with Bo Peep is to run from her, and she's a brutal warlord who's actually just a bully that he needs to face up to. So Anna really shows him the way," he said.

Once Upon A Time Season 4 Episode 2 appears to be a David-Anna episode. By the end of the episode, Oncers hope to find more clues if not answers as to what happened to Queen Elsa, Anna and Kristoff after the events of the "Frozen" movie.
