A seemingly impossible robbery at Queen Consolidated's Applied Sciences Division brings Central City police scientist Barry Allen to town. Citing a similar case back home, Barry offers to help Oliver and team with the investigation. Oliver senses there is more to Barry than meets the eye, but he's distracted by the similarities between this current case and something that happened on the island. Meanwhile, Felicity takes a liking to Barry, which doesn't go unnoticed by Oliver. Sin asks Roy for help when a friend of hers goes missing. Roy is surprised when Thea not only encourages him to help, but joins the search. Unfortunately, Sin's friend is connected to Brother Blood, and their search ultimately gets one of them seriously injured.

When Barry discovers the sedative being used in Blood's mirakuru formula is ketamine, his computer screen is shown with a diagram of the substance's molecular structure. What is shown here is very close to what medical grade ketamine's chemical formula looks like, but what is shown is the precursor to ketamine. Medical grade ketamine is actually racemic ketamine, the chemical formula shown on the screen is for racemic ketamine's enantiomer, known as (S) ketamine. A substance that is racemic has the same chemical makeup and structure as the original substance, but its structure is the mirror opposite, so in other words it looks like an upside down version of the original chemical diagram.
