Amy and Sheldon are again eating the fancy dining room and she wonders if Sheldon feeling guilty about being there when their friends have to eat in the cafeteria. No. Amy's publicity interviews are going well. She is his star of NPR Science Friday. In the magazine Wired, the article was entitled, “The Neurobiologist Who Revolutionized Physics.” Sheldon gasps about the “who” who did “what”?
The gang is getting ready for paintball. Penny asks about Amy’s interview and she downplays it since she knows that Sheldon is upset. Sheldon sasses that she is “The Neurobiologist Who Revolutionized Physics.” Penny understands. Anu is getting ready, but then finds out that Raj isn’t happy about what he saw. Denise and Penny volunteer to be captains. Denise first picks Leonard who isn’t used to being picked first. Penny picks Bernadette who is small and viscous. Denise takes Sheldon. Penny; Raj. Denise; Amy. Penny; Anu. Denise; Howard. And finally Penny takes Stuart after looking like she was still choosing among several candidates.
In the shed Denise leaves Amy and Sheldon to guard the flag. Leonard and Howard leave with Denise while Sheldon and Amy argue. She can revolutionize paintball while Sheldon has poor people skills.
Anu thinks it is fun sneaking around playing paintball. Raj accuses her of sneaking around. Anu accuses him of spying on her. Her ex-boyfriend stopped by to pick of some stuff. Raj wants to know what other “stuff” she was giving him. Then Anu asks Raj to delete her doorbell camera from his phone and to just trust her. Raj shouts at her that he barely even knows her. This causes a break since neither of them know why they are even planning a wedding. Denise then shoots Raj.
Stuart gets shot by Denise and quickly gives up. She shoots him again and wants to know why he’ll not move in with her. He runs away again.

The Coopers, Hofstatders, Raj and Anu meet back at the start. Anu wants to go home without Raj so the Coopers offer her a ride. Sheldon warns Anu that they are still in a bit of a spat.
Denise approaches the shed and finds the amorous Howard and Bernadette inside. Get out! Sorry. They throw out the flag which Denise happily carries off.
The next day Stuart shows up at the comic book store covered in bruises. He admits that he is also bruised on the inside. Stuart apologizes to Denise telling her that he doesn’t want to mess things up since things between them are going so good. To show her his seriousness, he gives Denise a key to his place. Of course it’s a key to Howard and Bernadette’s place so she can’t us it or even let them know she has it.

- Chuck Lorre's vanity card. 
- Caroline Preece at Den of Geek! - Sheldon doesn’t want to be left behind and so insists on being involved, but it immediately flummoxed by a question that asks whether the discovery is derivative of another’s work. When Amy takes over and is dubbed ‘the neuroscientist who revolutionised physics’, Sheldon is obviously upset. The episode culminates in a very well staged paintball tournament that forces each of the couples - yes that’s right even Raj and Stuart are coupled up now - to face up to their issues. Only Bernadette and Howard have nothing to resolve, but maybe it’s fun for them to just coast on into the sunset.
