Donna Sabine was Jules' replacement after Jules took a temporary leave of absence to recover from the gunshot wound she takes in S1 finale, "Between Heartbeats". A former undercover narcotics agent wishing to get rid of her "mask", Donna transferred to SRU's Team 3 upon Jules' return. She appeared in six Season 2 episodes: "Business As Usual", "The Fortress", "Clean Hands", "Aisle 13", "The Perfect Family", and "Remote Control". During her tenure on Team One, Donna took lethal action on two occasions.
