Continuity mistake: When Mohinder is back in India, his mother tells him that his sister Shanti died at the age of 5, when Mohinder himself was 2. In "The Hard Part", Mohinder tells Molly Walker that Shanti died before he was born, and shows her a photo of Shanti (who looks 5 years old) and his pregnant mother.
Trivia: There are a number of other Star Trek references in Heroes. In episode 15 (Run!), Hope refers to Hiro as "Sulu." George Takei, who played the original Sulu plays Hiro's father. And at one point (and several other times throughout the show) Hiro gives the Vulcan hand symbol that Spock always used when he would say "live long and prosper." Zachary Quinto, who plays Sylar, would also later play Spock in the 2009 reboot Star Trek.
