So far, no one is entirely sure who caused the accident that killed Patrick (Jason Thompson) and Sabrina's (Teresa Castillo) son Gabriel, but the truth may soon come out on General Hospital.

Sam Investigates The Accident?

Patrick has so far been hazy on all the details of the accident, and Sam (Kelly Monaco) has been investigating on his behalf to keep her mind off of her problems with Silas (Michel Easton) and Nina (Michelle Stafford). Now, however, Patrick may finally be finding his head clear up, and he could remember some important details about that fateful night.

"I remember something," he says to Sam in a preview clip for the Thursday, June 26 episode.

Rafe Has A Disturbing Memory?

So far, any number of suspects have been debated as possible culprits -- including Fake Luke (Anthony Geary) who had threatened to hurt Emma (Brooklyn Rae Silzer) hours before the crash, Ava (Maura West) who had told Carlos (Jeffrey Vincent Parise) she would cause Sabrina harm if he blabbed the truth about A.J., and Britt (Kelly Thiebauld), who arrived on the scene quickly.

However, another possible suspect in the crash is Rafe (Jimmy Deshler), whose drug problem recently surfaced, and he has had some disturbing memories of that night. Now, his strange behaviors as a result of the drugs may have been noticed by Kiki (Kristen Aldersen), and she will confront him about what's going on.

"I know what's eating you Rafe," Kiki said.

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