General Hospital Anniversary Promo Teases Reveal of Luke's Dark Secret

Loading video...

What does one give for a 52nd anniversary? Closure, apparently.

ABC’s General Hospital on Wednesday, April 1, will at long last reveal the truth about what caused Luke Spencer’s (Anthony Geary) psychotic break, as promised in the new promo above (which will air during tonight’s Grey’s Anatomy).

Guest-starring in the episode will be Dee Wallace (E.T.), as Luke’s long-lost sister Patricia, who will help answer the long-brewing, dark questions.

Also to mark the anniversary, select scenes from the sudser’s April 1, 1963 debut will be recreated, with current cast playing characters of yesteryear — including Jason Thompson (Patrick) as Dr. Steve Hardy, Rebecca Herbst (Elizabeth) as Nurse Jessie Brewer and Ryan Carnes (Lucas) as Dr. Phil Brewer. Y’all best do John Beradino, Emily McLaughlin and Roy Thinnes proud!

What’s your current working theory on what Luke/Fluke has been blocking? And does it involve Mitch Laurence…? (‘Twas a joke, kids.)
