Robert believes Holly is hiding a major secret, and on the Monday, Nov. 21 episode of "General Hospital," Robert will confront Holly with his suspicions.

In the promo video for the ABC soap opera, Robert (Tristan Rogers) asks Holly (Emma Samms) how long she has been working with Victor (Charles Shaughnessy). "GH" spoilers reveal Robert wants answers from Holly.

In the previous episode, Robert gave Holly false information about Anna's (Finola Hughes) case. He claimed to know the whereabouts of her safehouse, and Holly created a distraction to get the details from Robert's phone.

Holly later met up with Victor and shared the details with him. However, after passing on the tip to other authorities, they discovered an empty house, and Holly appeared shaken when Robert found her.

Now that Robert has confirmation that Holly is working with Victor, he will want answers. Will Holly finally reveal that Victor forced her to frame Anna for shooting Lucy (Lynn Herring), or will Holly convince Robert to drop the subject?

Elsewhere in the ABC promo video, Carly (Laura Wright) tells Drew (Cameron Mathison) that somebody knows about them. "General Hospital" spoilers reveal Carly lies to Sonny (Maurice Benard).

Although Carly and Drew need to keep their blossoming romance a secret to avoid the authorities investigating them for insider trading, Josslyn (Eden McCoy) managed to find out they are dating.

Carly has made sure Josslyn won't tell the secret, but it appears Sonny (Maurice Benard) will want to know more about Carly's meeting with Brick (Stephen A. Smith).

Viewers know Carly met with Brick to get supplies to treat Dex's gunshot wound, but she will not want to share the details with Sonny. It appears she will lie about why she met with Brick, but will her excuse strain Sonny and Brick's friendship?

Other "GH" spoilers tease Britt (Kelly Thiebaud) gets difficult news, Scott (Kin Shriner) has a warning for Cody (Josh Kelly), and Valentin (James Patrick Stuart) and Victor come face to face.

"General Hospital" airs on weekdays at 3 p.m. ET on ABC.
