During the beginning of the day, Danny was seen working silently alongside Edgar Stiles.
Later, Danny was seen removing the sensory deprivation equipment from Richard Heller following his torture, and left the holding room when Secretary of Defense James Heller entered to speak with his son.
Danny operated the cameras and other equipment behind the one-way mirror during the interrogation of Dina Araz by Tony Almeida. Tony called him into the holding room at about 5:30pm, and asked him to turn off the cameras to frighten Dina. He did so. Soon after, Jesse hesitated but left the viewing room with Erin Driscoll and another staffer when Tony asked everyone to get out, to further frighten the witness.
At 9:05:22pm, Danny handed Almeida a report from the medical examiner who examined the body of Dina Araz. Shortly after at 9:20, Danny supervised the planned interrogation of Behrooz Araz. While Eric Richards prepared his interrogation drugs, Curtis Manning spoke with Danny moments before Tony Almeida arrived.
After Curtis gave Behrooz a watch with a tracker in it, Danny "double tagged" him by injecting a microtracker into Behrooz's scalp as well.
Audrey Raines was framed by Collette Stenger as a mole, so Karen Hayes from Homeland Security decided to interrogate Audrey. Danny wheeled in an interrogation cart to Audrey's holding cell to prepare for a thorough interrogation by Rick Burke.
At 6:20am, Nadia Yassir ordered Danny to focus on conducting a search of the "main grid" of Los Angeles proper, because the FBI would be searching outside the city limits. They were interrupted by Chloe. Later, at 6:10pm, Mike Doyle directed Danny at a computer screen before going over to micromanage the work of Chloe O'Brian.
