Some serious secrets are about to be revealed on General Hospital as several residents start heading back to Port Charles.

Jason Escapes His Captivity

Robin (Kimberly McCullough) managed to successfully escape from the Crichton-Clark explosion alive-with Jason in tow-and the two are about to head back to Port Charles, where Jason's appearance will be sure to shock several people-as he has been believed dead for some time.

"We're almost home," Robin says to him in a preview clip for the Monday, September 22 episode.

Sonny Moves To Gain Control Over Ava Again

When Jason arrives back in Port Charles he will certainly be a presence that no one expects to see-and his return could spell some major drama for Sam (Kelly Monaco), who has been trying to move on following both his death, and the demise of her relationship with Silas (Michael Easton).

Sonny (Maurice Bernard) will also likely be shocked when Jason returns, though other news will stun him even more-like the revelation of just who happens to be controlling the Jerome crime organization.

Sam has begun investigating Luke (Anthony Geary)-unaware that his imposter is masquerading as him around town-following Spencer's (Nicolas Bechtel) confession that his uncle had threatened to harm Emma (Brooklyn Rae Silzer) if Spencer told anyone he had overheard his conversation about trying to take Sonny down. And the more Sam looks into the possible threats, the more she is realizing that the man everyone seems to believe is Luke is actually Julian (Michael DeVry) and Ava's (Maura West) boss-news she will need to share with Sonny as soon as possible.

"Do you think Luke was helping the Jeromes bring down your organization?" she asks Sonny in the clip.

General Hospital airs Monday-Friday at 3 p.m. on ABC.
