Events will grow even more intense in this week's episodes of "General Hospital."

Spoilers for the new episodes reveal that Paul will try to mess with Julian's murder trial, Andrew will join the hunt for the GH killer, and Hayden and Liz will face off.

On Monday's episode, Hayden will agree to donate the blood needed by Elizabeth Webber, but on the condition that she will give her back her diamonds. Liz will get confused with Hayden's offer, especially since she thinks that Hayden was the one who pushed her down the stairs.

Meanwhile, Hamilton will promise to help Hayden and have all the charges against her dropped soon.

As for Franco, he will turn to Kiki Jerome for advice as he gets torn about the sister secret, which will spill out by the end of the week. Kiki will ask Franco if she needs to back off with Morgan. What makes matters even worse is that Darby Collette will return in Port Charles to mess with both Kiki and Morgan.

Paul Hornsby will also try to get Julian Jerome's trial off track. Ava builds up her blackmail to ensure that her brother walks. However, making her freak out on the stand will be very easy since Alexis Davis is falling apart. Since Alexis is the key to the case, making trouble with her is the best way out.

As the week comes to a close, Julian will discover that he still has a chance to avoid imprisonment. Paul's sabotaging the case excites him and makes him confident that he could walk away from all the charges.

Andre Maddox will also get in to help with the GH killer case, and Dante will discover another piece of evidence. Paul closely involves himself in the investigation, but his real motive is to make sure that they won't find out it's him. His next victim is Monica, but someone will get in the way so he will be forced to kill that someone instead.

 The new episodes will also see a confrontation between Carly and Michael over Sabrina. Spoilers suggest that Tracy will also receive a devastating news, and it has something to do with the serial killer deaths.

The new episodes of "General Hospital" will air from September 12 to September 16 on ABC.
