He successfully managed to keep everyone in Port Charles from guessing that he wasn't the real Luke Spencer, but Fluke's identity could finally be revealed on General Hospital.

Bobbie and Michael In Danger

While the chance that he could be Bill Eckert back from the dead is possible, no one has put the pieces together just yet that the man walking around Port Charles is not the Luke Spencer (Anthony Geary) they all know and love, and that the man they all respect and admire is actually tied up in the basement of his childhood home.

However, after his sister, Bobbie (Jacklyn Zeman) and great nephew Michael (Chad Duell) arrive at the home to see if it would make a good location for the AJ Quartermaine memorial clinic and hear a commotion in the basement-Fluke could find his whole plot jeopardized.

More Answers Are Given About Fluke

"When you hear a creepy noise, you don't check it out!" Bobbie warns Michael in a preview clip for the Monday, Jan. 12 episode.

While the two have been in the house, Fluke has been in the basement with his captive, threatening to hurt everyone who means something to him-including Bobbie. And now, he could take things one step further. Instead of torturing Luke with his words and vague answers to his questions, he could start to physically torture him as well.

"1...2....3," he says tauntingly in the clip, as he swings a baseball bat in the direction of Luke's kneecaps.

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