[4] The episode received generally positive reviews from television critics, who praised Leonard and Penny's attempt to rework their relationship.
While playing Settlers of Catan, Sheldon, Howard and Raj ask Leonard why he's putting himself through another relationship with Penny, as they had broken up two years ago when things got too serious for her.
They tell each other about their work and Penny is amused when Leonard boasts that he built a Bat-Signal and calls himself "King of Nerds".
Later, Leonard is asleep and awakened by a text from Penny who meets him in the hallway, kisses him, takes him into her apartment and tells him to be quiet.
When Penny reminds him that he overthinks everything, Leonard finds himself back in the hallway, having been daydreaming while with Sheldon complaining about the Spock cardboard cut-out.
The arc concludes with the next episode "The Beta Test Initiation" where Penny and Leonard return from their date.
According to Bill Prady, co-creator of The Big Bang Theory, approval from Paramount, J. J. Abrams (producer of the new Star Trek series) and Zachary Quinto was required in order to mock Spock.
Day noted that revisiting Leonard and Penny on the 100th episode was the best way to honor the history of the series.
Though she was happy to see "Peonard or Lenny" back together, she felt that the other guys had the best lines with the "wood" jokes.
Overall she found the show "brought us back to the origins of the comedy and what made us fall in love with these nerds and their gorgeous neighbor."
