Tonight, Christophuh's ex-wife comes to town to drop his son off for some quality father and Bobby time, while the team solves the murder of a graffiti artist whose killer is harder to nab than it first appears. Don't know what that means, but the episode's official synopsis also says that Christophuh gets some news that puts him and all the other detectives in dire jeopardy. Something besides impending cancellation? That is rough.

Detroit 1-8-7 airs on ABC tonight at 10 PM, opposite The Real Housewives of Miami (Bravo), Tosh.0 and the Donald Trump Roast (both on Comedy Central, back to back), Lights Out (FX) and Teen Mom 2 (MTV).
