The Russian Rocket Reaction

Plot

NASA picks a deep field space telescope to go on the International Space Station and chooses the telescope Howard's team was working on. Howard is told he is going to the ISS with the telescope as a payload specialist. As NASA no longer has a Shuttle, Howard will go on the Russian Soyuz and jokes about its safety by referencing the Chernobyl disaster.

Bernadette (Melissa Rauch) is upset that Howard accepted the astronaut job without consulting her. Her father was a member of the police and as a child, she was always worried about him dying. She tells Howard's mother, who forbids him from going to space. Later, when talking to Penny (Kaley Cuoco) and Amy (Mayim Bialik), Bernadette thinks she may have made a mistake. She talks to Howard and apologizes, although his mother still refuses to let him go into space.

Sheldon and Leonard decide to start a sword collection with a sword from Game of Thrones and Leonard haggles with Stuart over the price, while Sheldon repeatedly begs him to just buy it. Wil Wheaton arrives at the comic book store and invites them to a party; while Leonard wants to go, Sheldon considers Wil Wheaton a mortal enemy. Sheldon says that Leonard is both his friend and not his friend, until he either goes or does not go to the party: he calls this "Schrödinger's friendship", in a reference to Schrödinger's cat. Upset, he compares Leonard's "betrayal" to turning R2-D2 and C-3PO over to the Empire.

Leonard is about to leave for Wheaton's party but gets a text that Brent Spiner will be at the party. He tells Sheldon, who pretends not to care but later attends. An excited Raj (Kunal Nayyar) brags that he has just met the gynaecologist of Alice Krige (who plays the Borg Queen in Star Trek: First Contact). Wheaton tells Sheldon that he wants to give him a Wesley Crusher action figure, remembering Sheldon's story of the convention where he didn't turn up. Sheldon is excited but Brent Spiner comes along and opens up the figure. He offers to sign a Data doll when he sees Sheldon is upset, but Sheldon declares Spiner his "mortal enemy".

Reviews

Oliver Sava of The A.V. Club gave the episode a rating of A-, describing it as "steeped in nerd culture". Sava said "Melissa Rauch and Simon Helberg have great chemistry" when talking about the main plot and enjoyed the subplot as well.

The episode was rated 53 out of 100 by "the TV Critic". The episode was said to be likeable "on paper" but that "in execution", it was an "odd story". The opening scene was described as "a weird one", given Sheldon developing his social skills and Leonard's politeness. The critic also said "I was sad to see the evil Will [sic] Wheaton character dispensed with" and summarized that "the actual script let everyone down".

Jenna Busch of IGN rated the episode 8.5 out of 10. Busch described the parallel of spats between Howard/Bernadette and Leonard/Sheldon as "a bit of a contrived plot", but said that "the Shrodinger's cat storyline was hysterical". Busch's only issues "were the lack of AFF [Amy Farrah Fowler] and Raj".

Carla Day from TV Fanatic rated the episode 4.5 out of 5. Day enjoyed when "Howard showed his maturity" and had mixed reactions to Sheldon and Wil's rivalry ending, saying that it was "comedic gold" and hoping that "we'll see more of Wil Wheaton". Wheaton has since appeared in several The Big Bang Theory episodes. and arguments over usage of money.
