JOIN STARS FROM ABC'S SUNDAY NIGHT LINEUP IN LIVE TWITTER CHATS

ABC will air all-new episodes of their hit dramas "Once Upon a Time," "Revenge" and newcomer "Red Widow" this SUNDAY, MARCH 10. During all three shows, fans will be able to join in conversations with talent and other fans on Twitter.

Fans of "Once Upon a Time" will not want to miss Sunday's all-new episode. A character will meet their doom in a pivotal episode that will forever change the balance between good and evil.

"Revenge" fans... there will be no more distractions! Emily Thorne is back, and in the wake of Amanda's tragic death, her lust for vengeance is stronger than ever.

In "Red Widow," Marta is surprised by her own criminal savvy when she's forced to broker a deal for Schiller, and her children become dangerously involved in the FBI's investigation.
