Previously on Big Bang Theory Season 8, we saw our favorite geeky gang attempting to hold a fake prom so they can have another interesting memory they shared together. While Leonard and Penny really had a great time dancing on the roof, Stuart's date and Howard's cousin didn't went that well. Then, there's also the stress that kept Sheldon Cooper preoccupied. When Amy confessed her romantic feelings, Sheldon surprised everyone by reciprocating the love. This week, another thing is going to keep the gang from enjoying each other's company. Catch the brand new episode tonight at 8/7c on CBS. You may also simply watch Big Bang Theory season 8 episode 9 stream through the free online stream link at the bottom.

After last week's show, actress Mayim Bialik gushed about her character's developing romance with Jim Parson's Sheldon. "The way our writers operate, it's not like a soap opera where every single plot line needs to be continued the following episode," she wrote. "We may let this sit for a bit to percolate, as we did the big kiss scene from last year... There is plenty of time to see what happens next. We are in no rush to overanalyze or over-identify (as my therapist says I tend to do) with what this means or doesn't mean for our characters."

The official synopsis of Big Bang Theory season 8 episode 9 reads: "When Leonard gets minor surgery on his nose, Sheldon is the one in need of sympathy. Meanwhile, Raj's parents' impending divorce causes Howard and Bernadette to work on their own marriage."

CBS's official show summary for Big Bang Theory reads: "Leonard and Sheldon are brilliant physicists - geniuses in the laboratory, but socially challenged everywhere else. Enter beautiful, street-smart neighbor, Penny, who aims to teach them a thing or two about life. Despite their on-again, off-again relationship in the past, Leonard and Penny have finally gotten engaged. Even Sheldon has found a female companion, entering into a "Relationship Agreement" with neurobiologist Amy Farrah Fowler. In their free time, Leonard and Sheldon enjoy fantasy role-playing games with their ever-expanding universe of friends, including fellow scientists Koothrappali, Wolowitz and Wolowitz's adorable microbiologist wife, Bernadette."
