The Big Bang Theory Season 9

The Big Bang Theory Season 9 :
Our two genius roommates Leonard and Sheldon and their friends are back once again (smarter but no wiser). Last season Sheldon went soul-searching (on a train of course) and was prepared to make some substantial revisions on his Relationship Agreement with Amy when everything changed. Leonard meanwhile was off to Vegas with Penny to finally tie the knot in the season finale. Howard finds himself alone with Bernadette after the sudden passing of his mother; while Raj is not only talking to women – he’s getting exclusive with Emily. Together they will all learn that life is far more complicated outside of the lab as love and friendship never produce predictable results!
