General Hospital might need to prescribe viewers a sedative. Based on the preview that ABC just dropped for the week of October 21, our blood pressure is going to be skyrocketing.

On one end of the canvas, Portia interrupts Marshall’s going-away party to announce that she has news regarding the infamous Heather Webber. And according to the spoiler that accompanies the video, the hook killer herself crashes the shindig. But, since Heather is still in custody — and the doctor has taken steps to ensure that she remains in custody — that hardly seems possible. So Portia’s news break must be how Heather’s presence is felt at the bash.

Elsewhere, Robert and Sasha are still reeling from Holly’s claim that they are father and daughter. While he probably wouldn’t mind if Robin had a half sister, Sasha chafes at the thought — and with good reason. If her mother is telling the truth, it means that her boyfriend Cody is also her cousin (since he’s Robert’s brother Mac’s son). Not that that kept Celia Quartermaine and Jimmy Lee Holt from getting together…

Of course, the big event of the week is going to be Sam going under the knife to donate part of her liver to significant other Dante’s comatose former wife, Lulu. Theoretically, the surgery should be a cakewalk; it’s performed all the time without complications. Alas, since we know that Kelly Monaco is being ushered to the exit, we’d be surprised if Sam wakes up after the operation.
