“Second Chances” packs a lot of punches—both literally and figuratively. After begrudgingly taking a mysterious case of people rusting away, Myka and Pete head to a small steel mill town in West Virginia to investigate. Jinks and Claudia take a trip to his hometown to find answers to him being free of the metronome. And back at the warehouse, Artie must contend with Mrs. Frederic about the astrolabe.
