His behavior has been a concern to several people for some time, but now, more Port Charles residents will begin looking into Luke's (Anthony Geary) strange behavior on General Hospital.

Ava Makes A Deal With Luke

Something has seemed off with him for a while, but no one had genuinely suspected anything was wrong until now, when his daughter, Lulu (Emmee Rylan) was kidnapped, and he made no moves to try and locate her. The behavior was suspicious, especially to his wife, Tracy (Jane Elliott), and now, it could result in his closest family members investigating him.

"I think I might know what's going on with Luke," Dante (Dominic Zamprogna) says to both Lulu and Tracy in a preview clip for the Friday, September 26 episode.

Sam Suspects Luke Could be Julian & Ava's Boss

The fact that Luke may have been responsible for getting Rafe to run Patrick (Jason Thompson) and Sabrina's (Teresa Castillo) car off the road, killing their infant son Gabriel, has also become a point of note-and Patrick and Sam (Kelly Monaco) will begin sharing what their investigation has turned up as well.

"So you have a lead? Somebody I know?" Alexis (Nancy Lee Grahn) asks them.

What none of them have figured out just yet is that the Luke Spencer who has temporarily left town isn't really the man they all know and love, but is in fact, an impostor who is masquerading as him while he fronts the Jerome crime organization. And even though both Julian (Michael DeVry) and Ava (Maura West) know that their boss isn't really Luke Spencer-even they don't appear to know his true identity.

Ava however, is more concerned at the moment with saving her own life. Her boss's identity isn't important because Sonny (Maurice Bernard) is trying to kidnap her so he can guarantee that after the baby is born, she'll be dead. However, her escape plans keep hitting obstacles.

This time, the obstacle is Morgan (Bryan Craig), who gave her a place to hide out for the night, but doesn't want her to leave town, because he knows it means he could potentially never see his child again.

"I don't want you to go," he says in the clip.

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