After six minutes into the show, you see Thirteen's ID badge says "Dr. Thirteen."
After the patient, Vince, mentions he might have mercury poisoning because he eats a lot of sushi, Thirteen replies, "And you're currently getting mixed reviews in 'Speed-the-Plow' on Broadway?" This is a reference to actor Jeremy Piven, who left the Broadway show "Speed-the-Plow" in late 2008, citing mercury poisoning as the reason. Piven claims that he ate sushi twice a day for 20 years.
Actor Rick D. Wasserman, who plays Vince, actually voices video game characters in real life.
The patient's fellow game developers are named Lee and Roy. This is a nod to the "Leeroy Jenkins" Internet meme/viral video which takes place within the online game World of Warcraft.
