Hades (Greg Germann) is ready to take Belle's (Emilie de Ravin) baby on the next episode of ABC's Once Upon a Time.

ABC has released a plot synopsis for next week's episode of Once Upon a Time, titled "Her Handsome Hero," and it looks to be a big Belle-centric episode.

"Belle turns to Rumplestiltskin [Robert Carlyle] with hope of finding a way to protect their child from Hades. However, they disagree over whether to use dark magic, as Belle forbids Rumplestiltskin from using his powers for evil," the synopsis reads. "Meanwhile, Hades secretly meets with Gaston [Wes Brown] in the Underworld and encourages him to seek revenge on Rumplestiltskin. As the heroes try to find a way to defeat Hades, Emma [Jennifer Morrison] has a terrifying nightmare that she realizes is beginning to come true. And in flashbacks, Belle and Gaston meet for the first time, but their blossoming romance comes to a halt on the eve of the Ogre wars."

In addition to Brown and Germann, guest cast for this episode includes Meghan Ory as Ruby/Red and Eric Keenleyside as Sir Maurice/Moe.

The promo for the new episode features Hades asking Gaston, "Wouldn't you like to finally get your shot at revenge?" Gaston also says at another point in the teaser "he killed me, and I'm gonna return the favor," referring to Rumplestiltskin.

In another scene, Belle asks Hades what he wants from her, to which the villain responds, "the thing you want most in the world. Your baby."

Once Upon a Time co-creator Adam Horowitz previously spoke about their plan for Belle in this part of season 5.

"We have plans to keep Belle busy. Although she didn't get on the boat [to the Underworld] with our heroes, she's important to the story and becomes very involved," Horowitz teased.

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