Spoilers from Zap2It
"Psych": Alternate universe episodes! After a party at which Shawn maybe celebrates a little too much, his reality splits up -- we'll see a world in which he and Juliet stay together, and a world in which they break up. Just Shawn's luck... there's a killer on the loose in both realities, and he or she seems to be on a quest to murder all of the Swedes in Santa Barbara. We're more concerned about which reality will turn out to be... well... reality.
