The series focuses on a number of identical human clones, all of whom are played by Tatiana Maslany: Sarah Manning, Alison Hendrix, Cosima Niehaus and Rachel Duncan.

[1] Tony's final look was created by Stephen Lynch, Sandy Sokolowski and Debra Hanson, in the show's makeup, hair and wardrobe departments, respectively.

[2] In response to the perception that Tony's introduction had created "a minefield of sexual politics", Fawcett said that that had not been the writers' intention; rather, their aim was to "just throw this character in there and treat them like a normal human being like we would anyone else on the show".

[5] The scene in which Cosima and Delphine use a vaporiser to get high was mostly improvised by Maslany and Brochu;[6] instead of inhaling actual helium, the pitch of their voices was altered in post-production.

[6] Manson chose to incorporate H. G. Wells' science fiction novel The Island of Doctor Moreau, which Ethan Duncan reads to Kira, into the episode since he felt that the novel's themes "run so deep in our show".

Mark Rozeman, writing for Paste, gave the episode a rating of 6.9 out of 10 and, despite enjoying several storylines, described the introduction of Tony as "perhaps the biggest misstep in the show's brief history".

[9] Slant Magazine critic Matt Brennan found the episode "jumbled and strange" but felt that the introduction of Tony was a "delightful twist".

He said that Cosima's storyline taking place at the Dyad Institute felt "dry and utilitarian, as though the writers realized they better get their shit together in time to wrap things up".

Club's Caroline Framke gave the episode a C− grade and criticised the "chaotic script", "aggressively flashy direction" and the failed attempts to integrate the "wildly different" subplots.

[11] Similarly, Adam W. Kepler of The New York Times felt that Tony was a cliché of trans men—"absolutely nothing [viewers] haven't seen before"—whose characterisation was overly simplistic.

[12] Although Chris Jancelewicz of The Huffington Post found Tony's character dull, he wrote in response to Maslany's portrayal of him: "Gift-wrap that Golden Globe, Hollywood Foreign Press.

[13] IGN's Eric Goldman felt that introducing Tony was a "big leap" for the show but that it paid off, largely due to Maslany's performance, and enjoyed the storylines featuring Alison, Cosima and Rachel.

[15] Conversely, Rob Hunter of Film School Rejects felt that her portrayal of Tony provided "proof that Maslany is human after all and capable of failure".
