Martin Querns sends the bikers from Emerald City to Unit B, including Jaz Hoyt. Later on, there is a confrontation between Hoyt, Ryan O'Reily and Nikolai Stanislofsky over the cell phone. Hoyt ends up getting sent to the hole and Nikolai gets sent to Protective Custody. Later on, Keller offers Bleacher an orange while inside their pod. Bleecher whips the orange at the door and a second later you can clearly see Hoyt in the background, raising his arms up at Keller and Bleecher. Hoyt could not have been at Emerald City because he was in the hole at the time and is not released from the hole until a later episode.
Dr. Nathan gives Cyril O'Reily 1 milligram of Haldol while he's restrained in the infirmary. The correct dose for Haldol is 5 milligrams. Further, Haldol is given intramuscular, not intravenous, in order to have a longer effect.
