Stephen Faber was the son of Monroe Militia officer John Faber and the member of the Rebels. Sometime after the Blackout, he joined the Rebels to fight against the Monroe Republic, presumably without the knowledge of his parents.
When the Faber family's maid, Rose, overheard that Stephen Faber had joined the Rebel cause, she reported her discovery to Julia Neville, who in turn told her husband Tom. Tom Neville went to Sebastian Monroe about Stephen Faber's affiliation, and Monroe sent troops out to find him. He was subsequently found with a band of rebels, and was executed on sight like the rest of them. This caused Monroe to question the loyalties of his father, although John Faber claims he and his son have been estranged for years.
