Brady was one of Sam Winchester's friends at Stanford University before and during his possession by a demon. After college, Brady worked at the Niveus Pharmaceuticals, led a small group of demons under his command and served the Four Horsemen of the Apocalypse, handling their itineraries as their "stable boy".
According to the demon, he possessed Brady sometime during Fall Break. Brady introduced Sam Winchester to Jessica Moore on Azazel's orders, the purpose being to kill her so as to force Sam back into hunting for revenge. Brady was the one that actually killed Jessica, Azazel just put the hit out on her.
Brady was seen as working for Pestilence and was a key player in the Horseman's plan to spread the Croatoan Virus throughout the world by disguising it as a vaccine for swine flu. As the head of Niveus Pharmaceutical, he ordered his unsuspecting human employees to begin mass-producing the vaccine and distributing it. He later killed one of the more uncooperative employees and used his blood to communicate with Pestilence.
Dean Winchester attempted to lure Brady into a trap by pretending to offer him a deal in exchange for the rings of War and Famine. However, Brady revealed that War and Famine would never return to full strength even if their rings were returned. He then attacked and beat up Dean. However, unbeknownst to either Dean or Brady, this had been part of Crowley's plan to capture Brady. Crowley snuck up behind Brady, put a sack with a devil's trap over his head, and knocked him out. Crowley then carved a demonic sigil into Brady's body, preventing him from smoking out or teleporting away.
Upon being brought to Crowley's hideout, Brady attempted to goad Sam into killing him. Dean, however, stopped Sam from doing so. Crowley then tried to get Brady to realize that Lucifer would exterminate all demons once he had destroyed humanity. Brady didn't believe this, so Crowley went and massacred a nest of demons, leaving one alive to spread misinformation that Brady had abandoned his post the other night and was working against Lucifer.
A hellhound was sent to capture Brady and broke into the hideout. However, Crowley brought his own hellhound which fought the other hound, allowing everyone to escape. Realizing that he would be tortured for eternity if Lucifer won, Brady gave up Pestilence's location. Crowley then left, leaving the Winchesters to deal with Brady. Brady taunted Sam again about how he'd let himself be manipulated his entire life. Sam responded by stabbing him with the demon-killing knife, killing him. Brady's body was left in the alley.
Shortly after the Winchesters defeated Pestilence, Crowley approached them with news of Niveus' swine flu vaccine. As Brady was VP of Distribution and working for Pestilence, they realize that he was working with Niveus to distribute the Croatoan virus and quickly put a stop to his plot.
