Robin (Kimberly McCullogh) may be set to leave Port Charles again, only this time it will be of her own free will, after she learns even more startling news on General Hospital.

General Hospital: Tuesday, Jan, 21, 2014

After previously learning that the new Chief of Staff at the hospital was her former captor, Dr. Olbrecht (Kathleen Gati), Robin tried strangling her. However, she will be turning her attentions to her husband, Patrick (Jason Thompson) next, as the truth about Sabrina's (Teresa Castillo) pregnancy comes out.

In a preview clip for the Wednesday, Jan. 22 episode, Liz (Rebecca Herbst) appears to be sharing the truth about who fathered Sabrina's baby with the married doctors.

"Patrick, there's something you should know," she said.

Patrick and Robin were aware that Sabrina is pregnant, but were lead to believe that Carlos (Jeffrey Vincent Parise) was the father, not Sabrina's former fiancé. If Liz reveals the truth however, it could cause Robin to re-evaluate how she feels about her husband and skip town.

The possibility of the situation is even more likely with confirmation from McCullogh herself that her contract to have a limited return to the soap is up, and she will be exiting the show once again in just a few weeks' time.

"I only have two weeks left," she said to ABC Soaps in Depth. "Next week and the week after."

McCullogh also revealed to Daytime Confidential that the leave would most likely be temporary once again, and gave fans a hint about what may cause her character to leave again.

"It's not goodbye. It's just see you later," she said before adding, "Robin's leaving because of her love for another character that is not Patrick on the canvas."

If and when the character returns to the soap, it would be interesting to see how this other love came to play in Robin's life when she was being held captive.

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