As the day progresses, Milo becomes aware of Nadia's emerging feelings for Doyle, a situation that reached a climax in Episode 21 (2:00 AM–3:00 AM). Milo tells Nadia that although he will be hurt, he will be okay if Nadia and Mike have something between them. Nadia tells Milo she doesn't know what she feels and needs time to sort things out. At 2:42 AM, Cheng Zhi's men invade CTU and take the entire building hostage. Zhou, the head assailant, then asks for the person who is in command. Nadia hesitates, and Milo steps forward and claims to be the Acting Director of CTU to protect her. A scared Nadia tries to signal to Milo to do nothing and sit down, but as he is asked to come forward, Milo looks at Nadia one last time and proceeds with his claim. Zhou then shoots him in the face, killing him instantly. Nadia is emotionally distressed after Milo's shooting, perhaps implying she was in love with Milo just as he was with her.
