When Eddie is being put into the patrol car after Olivia convinces him to give up, Olivia walks out of the apartment building and puts a police jacket on over her bulletproof vest. After a short conversation with Nick and Captain Cragen, Sergeant Mullen congratulates Olivia on a good job. The jacket is now around her upper arms and she puts it on a second time.
While searching Sandow's office Amaro finds a few prescription pill bottles, he says one of them is labeled "Quaalude". However methaqualone (Quaalude) was taken off the market in the US in 1982, and made a Schedule I controlled substance in 1984. It is also illegal in pretty much every country in the world and is not manufactured anymore, the only source of Quaaludes is from illegal drug labs. Ergo the Quualudes Sandow has would not have come from any pharmacy.
