Suddenly an FBI colleague alerts Booth that rogue sharpshooter Jacob 'Jake' Broadsky has killed again, this time fellow rifle art adept Matt Leishenger, whose gun and port access card Jake stole. As feared, the madman targets 'traitors', such as Booth and hence the whole Jeffersonian. Unsuspecting, Booth hands Nigel the cell-phone Jake takes fatal aim on.
