Robert ended up committing suicide with Joe's revolver, leading Joe to interrogated about it by Brass before asking for his lawyer. Later, he signs for Robert's personal effects and Sara discovers he is wearing an identical ring as Robert's. At a club, he and Robert's brother kidnap Catherine and leave her at a hotel.
