Stalkers, hallucinations, and guest stars, oh my! "The Young and the Restless" has it all going on next week. Get the details, below!

Still pursuing Jack, Mary Jane takes her crazy to a whole new (illegal) level. Far be it from us to question the citizenry of Genoa City, but umm ... how's a lady this nuts duping y'all? Like, time and time again?

Newly reengaged to his wife, Nick learns that his ex-wife Sharon (who is secretly carrying his baby) has broken up with Jack. Will this information make him wish he had waited just a little longer to reunite with Phyllis? We're not betting folk, but if we were, we might call this one a sure thing.

As her wedding day fast approaches, Nikki starts to have doubts. Will she marry Paul, or does her heart still belong to a certain ruthless Newman? And if she does marry Paul, can her wedding be as awesome as Billy and Chloe's, or Kay and Murphy's, or Cane and Lily's?

Ashley has an unnerving hallucination. Seeing as Raya Meddine will be appearing as Sabrina in two episodes next week, we have to assume this is the real deal, not Adam in a dress. Will her ghostly encounter spark the breakdown everyone's been fearing?

Also appearing in GC next week: Jeanne Cooper's real-life son, Corbin Bernsen, as Father Todd -- Paul and Mary Jane's brother (he played the role once before, five years ago). How cute were Jeanne and Corbin at last year's Daytime Emmys, when she won?

What do you want to see happen next week on "Y&R"?
