Hernandez discloses details about the shooting to Glynn and mentions Tarrant getting theballoon from Adebisi, who got theballoon originally from Clayton Hughes.

Morales asks Rebadow to do the deed in exchange for anything Rebadow wants and Rebadow accepts. Escapee Busmalis is caught and returned to Oz where he is rebuked by Rebadow. A 'fresh from the hole' Adebisi begins implementing his plan to get a new Em City administrator. A cell phone appears and Ryan schemes to get his hands on it. Like most O'Reily schemes, someone ends up dead and this case is no different as Hoyt's recruited to do the 'honors'. Said scores a victory for Jason Cramer and Shirley Bellinger gets a visitor.

OZ is set deep inside the Oswald Maximum Security Prison, in an experimental unit known as Emerald City. Em City focuses on prisoner rehabilitation over public retribution. There's one set of rules from the outside looking in, and another once you're inside. Every group - Muslims, Latinos, Italians, Aryans - stick close to their mutual friends and terrorizes their mutual enemies.
