Tread Perilously returns to the modern crime procedural with Bones. But its non-format fourth season finale may break Erik.

When Brennan and Mr. B learn a man was killed in their club, all their quirky employees are rounded up for questioning by Mr. B's cop brother. They all hold back key information as Brennan and Mr. B begin to suspect a possible culprit -- not that they're crime-solvers, mind you. As Mr. B gets caught up in a hostile takeover attempt and deals with a flamboyant local hip-hop artist, the gang slowly shows their hands leading to one inevitable outcome: none of this is happening and Brennan is writing the worst crime novel ever while Booth lay in a coma.

Erik tries his best to process what was supposed to be an amnesia episode, but turns out to be a strange mirror universe episode. Justin eventually explains all the "jokes," but they seem to thud in or out of context. A discussion of how heavy-set mafia types ensues while Erik decides it's amazing a cartoon about a Monster Truck Mafia never hit the airwaves in the 1980s.

Now here's Mötley Crüe.
