In The Big Bang Theory series finale, Sheldon and Amy win the Nobel Prize in Physics, but their success brings unexpected changes and complications. The gang deals with personal and professional issues while supporting the Coopers. Leonard finally rebels against Sheldon's controlling ways, and Penny reveals she's pregnant. The gang almost splits up due to Sheldon's behavior, but they reconcile at the award ceremony, where Sheldon delivers a heartfelt speech acknowledging his friends' support. Raj ends up dating Sarah Michelle-Gellar. While the final season was too Sheldon-centric, the finale satisfied fans by providing closure for each character.
