Plot

Leonard is forced to ask Penny to set Howard up with one of her friends, while Sheldon seeks payback against sci-fi star Wil Wheaton.

Howard reminds Leonard of a five-year-old pact between the two. Effectively, the pact stipulates that Penny has to set Howard up with one of her friends. Leonard has to tread lightly to ask Penny for this favor. A reluctant Penny does find someone, but she may regret it when she and Leonard go on a double date with them. Meanwhile, Raj tries to talk Sheldon into entering a $500 top prize Mystic Warlords of Ka'a tournament with him to be held at the comic book shop. Sheldon has no interest in entering because, with his eidetic memory, the game is no challenge. Sheldon changes his mind when he learns that Wil Wheaton, number six on his arch enemy list (Wil didn't show up for a scheduled appearance at a sci-fi convention that Sheldon attended in 1995), has entered. Sheldon's goal is to crush 'Wesley Crusher'. During the tournament, can Wil do anything to change Sheldon's mind about him?—Huggo

Now that Leonard is dating Penny, Howard reminds him of a pact they made that if one of them gets a girlfriend that he should ask his girlfriend to set up the other one with one of her friends. Leonard doesn't remember it but Sheldon does. So Leonard asks Penny and she reluctantly sets him up with a girl named Bernadette. They go on a double date, and they don't have anything in common which makes Leonard and Penny think it's a mistake. Sheldon goes to the comic book store and learns there's a collectible card tournament, Raj wants to enter and needs a partner and asks Sheldon but he doesn't think it will a challenge. But when he learns Will Wheaton will be joining he sees this as his opportunity to get back at him for not showing up at a convention he was suppose to attend which Sheldon went to.—rcs0411@yahoo.com

Penny is reluctantly playing "Mystic Warlords of Ka'a" with Leonard, Howard and Raj. Sheldon explains all the cards that she can play due to his Eidetic memory. Howard concedes that the game is over, which first excites Penny. Penny then immediately leaves, because the last time she didn't leave, she ended up playing Mystic Warlords of "Ka".

Howard then brings up their "Girlfriend Pact" with Leonard: if either one dated a hot girlfriend, they would have her find a date for the other. Leonard can't remember making the pact, but Sheldon promptly announces the date (June 30, 2004), place (Opening Day of "Spiderman II", AMC Theaters, Pasadena) and available concession stand snacks ("Only red Icees, no blue"). Leonard admits that he only agreed to the pact because he never thought he'd have a hot girlfriend, and he was positive Howard never would have one either. Raj was absent during the pact agreement due to his small bladder.

At lunch, Sheldon won't give Leonard a napkin out of his 4-napkin system (lap, hands, face and personal emergency). He offers to provide a guest napkin the next day for Leonard; this prompts him to take one of Sheldon's napkins (the face one) anyway. Howard continues to pester Leonard about having Penny find a "hot and tall" date for him. Leonard reluctantly agrees to talk to her about it. Sheldon makes fun of Raj's sweater vest. Raj announces that there will be a "Mystic Warlords of Ka'a" tournament at the comic book store, with $500 going as first prize and wants Sheldon to enter with him, but Sheldon isn't interested.

After sex, Penny tells him that he really is a genius, though Leonard admits that he had Googled his technique. Remembering Howard, he tentatively broaches the subject about pacts. Penny reminisces about a pact she made in the first grade with her friend, Rosie: to marry Bert and Ernie, Muppets from "Sesame Street". Leonard mentions his long-standing pact with Howard "which kind of involves [her]". This vague statement kills the coitus blissful mood, making Penny suspicious about its implications. Penny refuses to fix any of her friends with Howard. Leonard tries to convince Penny that, "deep down inside, Howard's a really nice guy". Penny retaliates: "The problem isn't what is on the inside. It's the creepy candy coating". Leonard pleads with Penny to reconsider it as a favor to him.

At the comic book store, Raj discovers that Wil Wheaton-as in Star Trek's Wil Wheaton (A.K.A. Ensign Wesley Crusher)--is signed up for the Mystic Warlords tournament. Stuart confirms that Wil lives nearby and is a big gamer. As a youth, Sheldon idolized Wesley Crusher on "Star Trek: The Next Generation" because they both had an Eidetic memory. In 1995, Sheldon rode 10 hours by bus, twice violating his personal rule of relieving himself in a moving vehicle, to a sci-fi convention in Jackson, Mississippi. He wore his Starfleet cadet uniform in order to meet Wil Wheaton and to have Wil sign his mint, in-package Wesley Crusher action figure; however, Wil didn't appear, and Sheldon pledged eternal hatred for him. Sheldon proclaims that Wil Wheaton currently ranks 6th on his All-time Enemies' List. He angrily teams up with Raj for the tournament (his alias as "Die, Wil Wheaton, DIE!")

As Leonard, Penny, and Howard head out on their double date. Penny had told her friend that Howard is an aerospace engineer, is fluent in 5 languages ("6, if you count Klingon"; women don't count Klingon as a doable foreign language), and that he has an unhealthy attachment to his mother. She was kidding about his mother, which Leonard silently comments will be a nice surprise for her.

Sheldon and Raj are playing in the tournament set up at the comic book store. Raj is gleeful about their progress, but Sheldon is consumed by his enmity towards Wil Wheaton. Sheldon wrathfully stares at an oblivious Wil Wheaton, still quoting Khan: "Wil Wheaton, my old friend. I've chased you 'round the moons of Nibia and 'round the Antares Maelstrom and 'round Perdition's Flames!" Raj remarks that Wesley Crusher was in the "Star Trek: Next Generation" franchise and thus, was unrelated to "Wrath of Khan", part of the original Star Trek series, but this does not deter Sheldon. Sheldon and Raj have to beat Lonely Larry and Captain Sweatpants before facing off with Wil Wheaton and Stuart in the championship round.

Howard awkwardly tries to make small talk in the car with Penny's friend, Bernadette (Melissa Rauch). She is working at the Cheesecake Factory in order to pay her tuition at grad school, majoring in microbiology. She doesn't understand his jokes and she doesn't share any of Howard's interests in science-fiction, role playing games (fantasy (Dungeons and Dragons) or bedroom), or magic. Leonard gloomily predicts that it is "going to be a long, long night".

Sheldon and Raj easily dispatches Captain Sweatpants and Lonely Larry in their tournament match. Sheldon balefully stares at their final opponents, namely Wil Wheaton, and he exclaims: "BortaS BIr Jablu'DI' ReH QaQqu' Nay'!" Wil Wheaton overhears it and asks Stuart in disbelief: "Did that guy just say "Revenge is a dish that is best served cold" in Klingon?"

At dinner, Howard continues to try and find common ground with Bernadette (she even doesn't like puppies!). Howard's mother calls and leaves a message on his phone. Bernadette is sympathetic, because her mother drives her crazy as well. They start sharing stories about how bad their mothers are, such as: their mothers continuously calls them on the phone about trivial things; Howard's mother made him wear rubber gloves to kindergarten for fear of catching diseases; Bernadette's mother still lays out her clothes and "wouldn't let [her] ride a bicycle because she thought [Bernadette would] hit a bump and lose [her] virginity." Bernadette freely discloses that she lost her virginity in a Toyota Camry, while Howard admits that he lost his virginity in a Toyota Corolla (to his second cousin). This shared revelation helps Howard and Bernadette warm up to each other. Howard then invites her to meet his mother for Shabazz dinner at home: "A Catholic girl like you, wearing a big cross like that, it might give my mother the big brain aneurysm I've been hoping for." Bernadette cheerfully agrees, with the proviso that Howard has to come to her family's Sunday dinner, wearing a yarmulke. Penny is happy that she is great at matchmaking.

Sheldon and Raj are finally playing Wil Wheaton and Stuart for the Wizards of Ka'a Championship. It is a tense match, surrounded by avid spectators. Sheldon ends up going head to head with Wil Wheaton, demolishing his competitor with his Eidetic memory. Before laying down the last card and winning the final match, Sheldon decides to give his monologue speech about his wrathful revenge to Wil Wheaton and the reason for it (i.e., the story of Wil Wheaton's absence at the 4th annual Dixie Trek Convention, the sci-fi convention that Sheldon had attended in 1995). Wil then reveals that he was absent from the sci-fi convention due to the death and funeral of his grandmother. Wil apologizes with such sincerity to Sheldon that Sheldon completely empathizes with Wil's loss: "If anything happened to my Meemaw, I would be one inconsolable "Moonpie"". Sheldon becomes wracked with guilt and loses the game on purpose (with his Enchanted Bunny card), despite Raj's loud protests. Wil smugly admits he lied about his grandmother's death. Actually, his "Nana" is alive and will be very happy to hear that he won (with Wil's Small Rock card killing Sheldon's Enchanted Bunny card): "Game over, Moon Pie!" Sheldon sits in shocked disbelief. After Sheldon realizes that he's been tricked, he yells in Khan-like fashion, "WHEEEAAAAAATTTTTTOOOONNNNNNNN!!!!!!!" The camera pans out to a global satellite image of Earth, mimicking a memorable scene from the blockbuster 1982 feature film Star Trek II: The Wrath of Khan.
