To the police, it adds up to easy guilt, but to Charlie, it indicates that Franklin has stumbled onto something that likely comes with life-threatening complications. Charlie wants proof the case doesn’t involve a double-cross, and when the Mack Investigations team throws all their assets at the case, Charlie's girlfriend, Mandy begins to worry that Charlie’s all-out efforts to find Franklin might be driven by lingering romantic feelings. In the end, everyone involved must figure out which loyalties run deeper than love.
