In the upcoming second episode of Season 4 of ABC's Once Upon a Time, fans will be introduced to a "brutal" character whose reputation in history is anything but brutal.

Theme Of Once Upon a Time Season 4: "Never Give Up On The People You Love"

The second episode of the season is titled White Out and features the introduction of Bo Peep (Robin Weigert), the seemingly innocent sheepherder who has lost her sheep. However, in the Once Upon a Time version, she is described as a "brutal warlord," according to a new plot synopsis released by ABC.

"In the Enchanted Forest of the past, Anna [Elizabeth Lail] tries to teach a meek David [Josh Dallas] to fight Bo Peep, a brutal warlord who is threatening to take his and his mother's farm away if they don't pay her price," the synopsis reads.

This will certainly provide David/Charming with some interesting new material.

Meanwhile, back in present day Storybrooke, it seems that Elsa (Georgina Haig) and Emma (Jennifer Morrison) will be spending a lot of time together in this episode.

"While desperately trying to find her sister Anna, Elsa is startled by Emma and accidentally traps them both inside an ice cave, with the frozen temperature placing Emma's life in peril," according to the synopsis.

Meanwhile, "Regina [Lana Parrilla], depressed over her likely breakup with Robin Hood [Sean Maguire], secludes herself away from the town and Henry [Jared Gilmore], which saddens her son. And with the townspeople considering Mary Margaret [Ginnifer Goodwin] their leader, she faces her first leadership task in trying to re-start a generator and restore the town's electricity after Elsa freezes and damages the power lines."

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