The finale revolves around the shocking revelation that is not actually dead.
Rose admits she kidnapped Charlie four years prior after finding him in Paris with a hooker, a mime, and a goat. She kept him held captive in a pit in her basement until he recently escaped.
After escaping, Charlie sends threatening messages to Alan, Walden, and Evelyn while mailing large checks to his former girlfriends and Berta.
In a highly meta ending, a figure resembling Charlie (viewed from behind) approaches the beach house. Just as he rings the doorbell, a helicopter drops a grand piano on him. Series creator Chuck Lorre then appears on screen, says "Winning," and is also crushed by a falling piano. Notable Guest Stars
