CBS has put out the press release for the eighth season finale of The Big Bang Theory, "The Commitment Determination", which airs this Thursday, May 7.  Full story


On their date night, Sheldon and Amy kiss on the couch in the apartment. Sheldon breaks off from kissing to ask Amy for her opinion on whether he should start watching The Flash TV series. Amy is upset that Sheldon is thinking about something so trivial when they're supposed to be spending some romantic time together on the fifth anniversary of their first meeting each other.

As Raj and Emily shop at Stuart's comic book store, Stuart prods them to hurry up as he wants to get home to Howard and Bernadette's where she's cooking meatloaf for dinner. When Emily finds a creepy decorative skull in the store, Raj is a little freaked out by her tastes but decides to buy it for her anyway.

When Leonard and Penny return home to the apartment, Sheldon asks them for their opinion why Amy's upset with him. Penny tries to explain to Sheldon why Amy is right to be angry with him, but he doesn't see it. Meanwhile, Raj joins Howard and Bernadette as they prepare dinner. Raj is creeped out by Emily's desire to have sex in a graveyard, so he's considering breaking up with her. Howard and Bernadette don't think Raj will break with up somebody who's sleeping with him.

As Sheldon, Penny and Leonard eat dinner in the apartment, Sheldon is still stirring about Amy, who hasn't spoken to him for twenty-four hours. Penny thinks Amy is right to feel upset that her and Sheldon's relationship is moving too slowly, but Sheldon doesn't see it that way. Sheldon points out that Leonard and Penny still haven't set a date for their wedding, angering Leonard and Penny who don't appreciate their relationship being put under the microscope Elsewhere, Bernadette is angry that her yogurt has been eaten by Stuart. Bernadette and Howard decide it's time to tell Stuart to move out of their house.

While Leonard and Penny wash up after dinner, Leonard wonders why they still haven't set a date for their wedding. Later, Sheldon apologizes to Leonard and Penny for causing trouble, though they realize it was helpful for them to think about their relationship. Penny points out they're free tonight and Vegas isn't so far away, so they decide to go and get married there and then. Meanwhile, Raj and Emily are at a graveyard, where Raj struggles to feel comfortable. Elsewhere, as Stuart pulls up at Howard and Bernadette's house, Howard tries to leave Bernadette with the job of telling Stuart to move out. Bernadette tells Stuart they need to talk, while Raj says the same to Emily.

As Bernadette and Howard try to tell Stuart to move out, he praises them as superheroes for putting up with him in their house. Stuart then receives a call from his father to wish him a happy birthday. In the end, Howard and Bernadette end up giving Stuart cake and singing Happy Birthday to him. Meanwhile, after Raj tells Emily that he thinks they're both very different, Emily asks him whether he's trying to break up with her. After Raj denies this, Emily says if he wants to break up with her, he'll have to do it himself. Raj tells Emily he was trying to tell her he loves her.

As they drive to Vegas, Leonard and Penny are excited at the prospect of finally getting married. After Penny says they're getting married with no regrets, Leonard feels the need to tell Penny about a kiss between him and another woman during his North Sea expedition. Penny feels Leonard is only telling her about this to sabotage their night, but Leonard says he only did it to be truly honest. Penny thinks she can look past Leonard's indiscretion and they should still get married.

Back at the apartment, Amy video calls Sheldon. As Sheldon begins to tell Amy he's been thinking about their relationship, she interrupts Sheldon to tell him she needs a break from their relationship. Sheldon is shocked, but tells her he understands. After the call ends, Sheldon turns to the Gollum figure on his desk and asks him what to do about an engagement ring.
