The Big Bang Theory Season 9 Spoilers: Everything We Already Know

The wait is almost over. Four months after we left the Big Bang Theory gang with several tantalising cliffhangers, they're back on our screens with lots of questions to be answered. Will Leonard and Penny finally get married? Leonard dropped a bombshell on their way to be married in Vegas, casting a long shadow over the one situation that looked beyond doubt. Aside from them, so many situations could have been tied up in the finale, involving almost every character. Stuart remained living with Bernadette and Howard despite their efforts to shift him, Raj opted to declare his love for Emily rather than his intended break up from their eerie, occult-ish relationship, and of course, the solidly non-moving relationship between Sheldon and Amy broke down sending the internet into meltdown.
