Zorin Brasha, an Albanian terrorist known as Teflon because the charges never stick, bashes in  the head of a delivery driver, John Coogan with a crow bar when they fight over a parking space. 

When John Coogan agrees to testify, Brasha threatens his life and his family's. He's even sent photos of his niece in Delaware with a note saying they'll send her to New York in pieces so John backs down during the lineup

Danny and his new boss, Lt. Carver butt heads but then bond over trying to find a way to convict Brasha. They both work to get a scared bodega owner to turn over his security video showing Brasha attacking Coogan.

When Brahsa escapes before he can be re-arrested, Erin makes sure Tori sees the video of Brasha assaulting Coogan. Tori tells Erin the name on Brasha's new passport. Brasha is arrested in Uruguay but will be extradicted to Serbia where he has charges pending. Frank isn't happy New York won't get to prosecute but agrees that Brasha being behind bars somewhere is a good thing.
