When Danar beams aboard the Enterprise, he attacks O'Brien and the security team that is waiting for him. Several times, O'Brien calls for more security, but no one shows up, except Riker and Worf, who are already on their way.
When Worf meets the turbolift supposedly carrying Danar, the door markings indicate that he's on deck 12. However, the security cells that Danar had just escaped from are on deck 36.
After the Danar and the prisoners on the planet start to riot, Picard tells Troi, Data and Worf to accompany him to the planet and they leave the bridge and head to a transporter room. Riker accompanies them part way, but neither he nor the captain tell anyone else on the bridge that they are in command of the bridge.
