Charles “Chuck" Bartowski was the son of Stephen and Mary Bartowski as well as Ellie’s brother. He was an anxious Nerd Herd associate at Buy More who unwittingly downloaded the intersect, an entire CIA/NSA secret database, subliminally into his brain, turning him into a human version of the intersect.

He was able to “flash” on any information within it. At first he wanted the intersect removed but eventually embraced the spy life. The CIA and the NSA concluded that Chuck must be protected and assigned Sarah and Casey jointly to the task. Chuck and Sarah became romantically involved and eventually got married. Sadly this was short lived as Sarah’s mind was wiped by Nicholas Quinn.
