Summer Glau (born "Summer Lyn Glau" on July 24, 1981, San Antonio, Texas) is an American actress, known for playing River Tam in the science fiction series Firefly and follow-up film Serenity, the television season Dollhouse and for playing Cameron in the series Terminator: The Sarah Connor Chronicles.
In "The Terminator Decoupling", the gang takes a train ride instead of an airplane; as Sheldon insisted on the train ride all the way to San Francisco for a conference. On the train, they discover sci-fi actress Summer Glau is also on the train. Soon, Raj, Leonard and Howard fight over who would go over to talk to her. While Howard thinks of a clever line to say, and finally finds a suitable one, Raj heads over to Summer with a beer in the hand, and steals his line, instantly making a good impression. He later discovered he was drinking non-alcoholic beer. When he notices the bottle, of course, he quits talking. Wolowitz then takes over and creeps Summer Glau out. Leonard eventually gets his chance, but she gets off the train before he can introduce himself.
