to certain doom". Mentions outside Stargate Following from his appearance in "Brain Storm" along with Bill Nye and Neil deGrasse Tyson, Rodney McKay is later mentioned by Bill Nye in the episode "Let It Go" of the third season of Blindspot. Conceptual history David Hewlett portrayed McKay in "48 Hours" and "Redemption" in the sister show Stargate SG-1. McKay's citrus allergy was the producers' in-joke about a SG-1 crew member who insisted he was violently allergic to citrus and thus refused going out to lunch with others, not knowing the local restaurant regularly served him salad containing citrus without anything happening. When the new Stargate Atlantis production crew came up with the casting, they originally created Dr. Benjamin Ingram, an African-Canadian scientist. Hewlett auditioned for the character, despite not being African-Canadian. It was decided that McKay would replace Ingram as a main character for the series. Hewlett was contacted and arrived at the set the day after filming for the Stargate Atlantis pilot episode had started. Producer Joseph Mallozzi described McKay as "an insufferable ass [in "48 Hours"] who, over the course of the franchise's run, ended up redeeming himself in surprising fashion." According to Mallozzi, McKay "takes another giant step toward redemption [in "Redemption"] – a process that would be completed by the time he assumed a lead position in the Atlantis expedition" and that "He's snarky, smug, and annoying as hell but – damn – he is good at what he does. And what he does is use his smarts to save the day."
