In the episode, Liz Lemon (Tina Fey) is opposed to going to her high school reunion, but her boss, Jack Donaghy (Alec Baldwin), manages to convince her otherwise.
Meanwhile, Don Geiss (Rip Torn) wakes up from his coma only to inform Jack of his decision to remain CEO of General Electric (GE).
Jack in search of a drink ends up at the reunion as well, and is mistaken for a former popular student Larry Braverman and still unhappy with Geiss' decision, takes on the persona.
"Reunion" was written by 30 Rock supervising producer Matt Hubbard, making it his fifth writing credit after "The Rural Juror", "Hard Ball", "The Collection", and "MILF Island".
In this episode, Liz says the line "I want to go to there", twice, which according to series creator, executive producer and lead actress Tina Fey was "coined" by her daughter, Alice.
[9] In an interview with the New York Daily News, Jane Krakowski, who portrays Jenna Maroney, revealed "Some of the great catchphrases of 30 Rock have come from Alice.
[21] IGN contributor Robert Canning gave the episode an 8.9 rating out of 10 and wrote "...the real reason to watch, as always, was Tina Fey and Alec Baldwin and their fantastic comedic performances."
"[23] Like Sepinwall, Bob Sassone of AOL's TV Squad was favorable to Jack going to the reunion, but most enjoyed the character impersonating Larry Braverman, observing it was a "well-used plot device" as Baldwin "made it believable".
The reunion plot was so strong, and the Carrie finale so inspired, that I hope the viewership ratings reflect positively and encourage a continuance of this creative trend.
Club's Nathan Rabin wrote that he was "much more amused" by Rob Sussman's "still-simmering rage" against Liz, because he "scored many of the show's biggest laughs."
He said that he found the second plot "a little underwhelming though I thought there was a neat meta-textual element to it", but wrote that it "scored some nice shots at the vapid narcissism of actors but it promised more than it could deliver.
Medina disliked that Tina Fey's Liz was portrayed in "unlikable light", and after insulting her former classmates at the high school reunion it "seemed a bit uncharacteristic and unflattering to her character.
