As Lulu (Emmee Rylan) and Dante (Dominic Zamprogna) receive some potentially earth-shattering news, Patrick (Jason Thompson) is set to be devastated by something else on General Hospital.

Liz Confronts Britt

After reuniting with his previously-assumed dead wife, Robin (Kimberly McCullogh), he was dealt information that his former fiancée Sabrina (Teresa Castillo) was pregnant. His impending fatherhood with another woman so far hadn't affected his relationship with his wife, but in a preview clip for the Monday, Feb. 17 episode, he will still receive a shocking announcement from Robin.

"Patrick, I'm leaving Port Charles," she said to her stunned husband in the clip.

Nikolas Prepares to Propose

What Robin's departure will mean for the couple's complicated relationship remains to be unseen.

Meanwhile, Lulu and Dante will receive a visit from Elizabeth (Rebecca Herbst), who comes to tell them the shocking news she uncovered while investigating Britt (Kelly Thiebauld). Britt's son Ben, who she supposedly had with Brad (Parry Shen), is actually their biological son because Britt injected herself with the couple's embryos.

"I have something important I need to discuss with you," she said to the couple.

Dante and Lulu are not the only ones who will be shocked by the news. Nikolas (Tyler Christopher) will learn the truth as well as he prepares to propose to Britt, though his girlfriend will try to spin the story in a way that makes Elizabeth look equally as bad.

"You have something to tell me?" Nikolas asked Britt in the clip.

"It's about Elizabeth..." she replied.

General Hospital airs Monday-Friday at 2 p.m. on ABC.
