When Sheldon petitions Wil Wheaton to appear on the new Professor Proton show, Wil offers a role to Amy instead. Also, Penny gets angry when she thinks the female protagonist in Leonard's novel is based on her.
Amy exits the bedroom and wonders why Sheldon is fixing a sandwich when they were supposed to go over to Leonard and Penny’s. Their friends are going to watch the new Professor Proton show and Sheldon doesn’t want to watch Wil Wheaton doing it. Sheldon is planning on complaining about it without ever watching it. Amy suggests that they watch it together so he can find specific points to criticize. Watching the show, Wil describes how they are going to build a hovercraft out of some common items that actually gets Sheldon excited.
Penny enters her apartment to find Leonard clattering away at a typewriter. Actually he had a new keyboard that makes typewriter noises so he could feel like a real novelist. He is working hard on his novel as his hero Logan Dean arrives at the CERN collider in Switzerland. Leonard quickly realizes what murder weapon he could use. Penny asks if it’s a Swiss Army knife, which Leonard admits is even a better idea.
Back in apartment 4B, Sheldon and Amy are having fun with their toy hovercraft. Then on the show Professor Proton tells his science joke of the day and he introduces a real astronaut – Howard Wolowitz. Sheldon is mad that Wil didn’t ask him though Amy points out that he did launch an Internet petition against him.
During lunch at work, Leonard is describing his novel where his hero discovers a new atomic particle, the gluino, AND a murder. Howard suggests that he talk to Bernadette since she has been watching lots of detective shows while confided to bed. Sheldon joins them and immediately forgives Howard without explaining what Howard did. Howard just accepts it. It was for not telling Sheldon that he was going to be on Wil Wheaton’s show because he would get difficult and annoying. This admission surprises everyone. Also, Howard adds that if he wants to be on the show, he should apologize to Wil.
Leonard is pacing while Bernadette reads his mystery novel. She is enjoying it and has no idea who the murderer is. Neither does Leonard. Bernadette then asks if Penny knows that one of his characters is based on her - Ilsa, the head of the institute who is a confident, ball-busting beauty that keeps rolling her eyes at the hero.
Ilsa replied, “Figure that out yourself, genius?”
Logan replied, “Okay, no need to be snarky.”
Ilsa looks at him suspiciously, “Who would want to kill him?”
Logan looks around the room. “Could be anyone. Dr. Silvers. [Howard look-alike] Dr. Prekash. [[[Raj]] with a goatee] Hans the janitor. [Stuart with a big mustache] But the door is locked, so it has to be someone in this room.”
“Wow, you are on fire,” snaps Ilsa walking away.
Back: Leonard wonders if Penny would be flattered. Bernadette thinks that Ilsa is pretty mean, not unlike Penny sometimes.
Wil Wheaton answers his front door to find Howard who apologizes for having brought over Sheldon. Wil wonders sarcastically if Sheldon has moved him to his super-secret enemies list. No, Sheldon doesn’t have one because he is not a Bond villain. Sheldon tells Wil that he is no longer on his enemies list, which doesn’t seem to mean anything to Wil. Howard gets Sheldon to say he was sorry and he tells Wil that he enjoyed his show. Sheldon also says that he’d loved to be on the Professor Proton show since it is a childhood dream of his. Wil remarked that he’ll keep Sheldon in mind, but wonders whether Amy would like to be on since he wants to promote women scientists. Sheldon hems and haws for a moment and then proposes that he and Amy both be on the show so that women scientists known that they can land a man.
Back at home, Penny tells a nervous Leonard that she likes his novel and can’t wait to learn who the killer is. She also finds the Ilsa character kind of mean much like Bernadette whom she is sure that Ilsa was based on.
Novel: Logan tells everyone, “But the door is locked, so it has to be someone in this room.”
“Wow, you are on fire,” snaps Ilsa walking away. [Bernadette]
Back: Leonard agrees with Penny.
Novel: Logan continues with his analysis. “Each one of you had a motive.”
Dr. Silvers asks, “Who died and made you detective?"
Logan points to the dead body, “He did.”
“I think you’re neglecting your own motive, a massive inferiority complex,” snaps back Ilsa.
“It’s not massive. Just average size,” replies Logan less confidently.
Hans the janitor breaks in, “I don’t mean to interrupt, but somebody’s tracking blood everywhere so – never mind, it’s me.”
Dr. Prekash says, “You say we’re all suspects.”
“How do we know you’re not the killer?” asks Dr. Silver to Logan.
“I have an alibi.”
Ilsa snaps at him, “Yeah, he’s not smart enough to pull off a murder like this.”
Back: Leonard claims that Ilsa wears glasses like Bernadette even though it doesn’t say that in his novel. Leonard walks off trying to convince her that the mean boss is Bernadette.
Amy is working on her computer when Sheldon returns and asks if she would like to be on television on the Professor Proton show. She isn’t really interested. Sheldon felt that she would want to promote science for little girls, but she doesn’t want to be in the middle of Sheldon and his love for the show. And she doesn’t want to upset Sheldon, who finds that situation very upsetting. Amy admits that there are other things she doesn’t do so Sheldon won’t get upset.
Penny is sitting on Bernadette’s bed hanging out because Leonard is working late. Bernadette mentions that Leonard should stop by and that she enjoyed his book. Penny wonders if the Ilsa character bothered her. Bernie then mentions that Leonard said that it was based on Penny. She realizes that he left when they were talking about it and she now knows what he meant. Son of a bitch!
In the Caltech cafeteria, Sheldon starts talking about the distressing news how Amy doesn’t do things so that he won’t get upset. Howard tells him that everybody does that all the time. Sheldon asks if everyone walks around on eggshells to spare his feelings. He doesn’t want to have that kind of relationship with Amy. Sheldon insists that he is going to change.
Penny is reading the book trying to determine if the Ilsa character was her.
Novel: Logan is lying against a desk wounded.
Ilsa observes, “It looks like the bullet went straight through you. Damn it, Logan. When are you gonna stop?”
Logan replies, “I didn’t get my PhD in quitting.”
“He’s losing a lot of blood,” remarks Dr. Silver.
“Great. I’m gonna have to clean that up!” complains Hans.
Dr. Prekash suggests, “You know, a little soda water might get that right out.”
Dr. Silver pleads, “We’ve got to find some bandages.”
Ilsa shouts, “No. There’s no time,” as she tears off her sleeve placing the cloth on Logan’s shoulder. “Does it hurt?”
“Everything you do hurts,” Logan replies.
“Then why do you keep coming back for more?” she asks.
Back: Leonard returns. Penny is pissed because she thinks that Leonard feels that she is mean and that everything she does hurts him. Leonard stammers as Penny storms off telling him to write whatever he want.
In 4B, Sheldon and Amy are playing chess and Sheldon lets her win. Amy wants to know what is going on. Sheldon says that he is responding with humility and admiration. He wants her to be able to do things she wants to do without having to consider upsetting him. There might be a little girl out there that might get inspired to become a brilliant successful scientist like Amy. "Thank-you, Sheldon." Amy really appreciates his compliment until he finishes that she is really bad at playing chess.
Now Leonard is talking to his mother that he might be subconsciously writing about Penny. Beverly corrects him and wishes that she didn’t have to do it all the time. She adds that he is a physicist and what does he know about writing a book.
Novel: Ilsa leans over the wounded Logan. [Beverly]
“You’re a physicist. What makes you think you can solve a crime,” asks Ilsa.
Back: Leonard leaves his mother as she again corrects his grammar. He runs over to Penny to tell her that she was writing about his mother, not his wife. Penny then imagines the story.
“I think you’re neglecting your own motive, a massive inferiority complex,” snaps back Ilsa. [Beverly]
“It’s not massive. Just average size,” replies Logan less confidently…
[Later] Dr. Silver pleads, “We’ve got to find some bandages.”
Ilsa [Beverly] shouts, “No. There’s no time,” as she tears off her sleeve placing the cloth on Logan’s shoulder. “Does it hurt?”
“Everything you do hurts,” Logan replies.
“Then why do you keep coming back for more?” she asks.Logan admits, “M..maybe, I do.”
Back: Penny is looking weird with that dialog between Leonard and his mother. Leonard then storms out wondering why he was even writing a book since he was a physicist.
Sheldon and Amy are watching the conclusion of Professor Proton with Amy appearing on it. Wil says that it was a pleasure to have her on. Amy points out that one can feel that pleasure if you don’t have a lesion in one's nucleus accumbens in their brain. Sheldon tells her that she was glowing even if it was only her oily scalp. Sheldon tells her how proud he was; while she can tell how hard he was trying to hold it in. Amy heads off to bed so Sheldon can go up on the roof and scream at the top of his lungs.

- Milka Väinämö at Tell Tale TV Though it could be flattering to have someone base a character on you, in that situation you would likely want that person to cast you in a positive light. The way Leonard has written about Ilsa, a blond eye-rolling and mean character with a striking resemblance to Penny does not really show her in a positive light...As The Big Bang Theory prepares for the likely wedding episode, a lot of screen time has been spent on focusing on the ways in which Sheldon is growing and changing as a person. As he learns that both Amy and his friends have been stopping themselves from doing or saying certain things just to make sure that he doesn’t get upset he realizes that something has to change. He does not want anyone, especially Amy, to bend over backward just to please him. This is MAJOR! M-A-J-O-R!..As an advocate of getting women out there doing the things they do best, I loved the fact that Amy decides to go on Wil Wheaton’s show to inspire young girls to get interested in science.
