After convincing Oliver to let him drive for the day, Chris gets help from a street guy he knows to find another contaminated victim. Meanwhile, Sam and Nick question the bartender who sold the Midnight Heroin to the OD victim’s ex. This leads them to name of his supplier. It’s someone Blackstone knows well. Sam and a team raid the dealer’s place. They find the drug supply but the Midnight Heroin is clean. They are back to square one.
Traci realizes that all of the contamination victims were in attendance at the first victim’s ex-boyfriend’s art auction. Someone spiked the guy’s supply with Anthrax. Dov knows that the husband he questioned is a veterinarian. He has access to Anthrax. He spiked the ex’s drugs because he was sucking his wife back into her world of addiction. He didn’t mean to hurt anyone but the ex. With the case closed, Chris lets Oliver know this was his last shift. That’s why he was grateful for the opportunity to drive.
Gail tries to get some info from Blackstone on what he observed while he was supervising Andy and Nick during their undercover operation. She learns that Nick could have come home during his stint but chose to hang out with Andy instead. In other news, Dov gets the 411 on bipolar disorder from a doctor. Extreme cases can be serious. Chloe freaks out on Dov when he accuses her of having the disorder. Their date is officially off. Gail, on the other hand, makes a date of her own. It’s not with Nick though. She leaves the Penny with Jacob Blackstone instead.
