Bitters first appears in Oh Captains, My Captains, nervously answering Caboose's Blue team to refer Grif's squad as "Orange team" rather than "Gold team" during a training exercise. After Grif, Simmons, and Caboose crack under pressure, Bitters and the rest of Gold team clumsily fall on top of New Republic reinforcements in confusion. Later on, Bitters is chosen to be a part of Grif, Simmons, Caboose, and Tucker's rescue team, along with Jensen, Smith, and Palomo. During their training the four recruits are given helmet cameras to record their sessions, but are laughed upon by the other Rebel soldiers for their failures. 

Afterwards, Bitters and the other Rebel soldiers discover a message from the Red and Blue captains detailing their departure. In response to this, Bitters and the recruits continue to train on their own, but are unfocused due to the departure of their captains. When Felix informs them of the Reds' and Blues' supposed deaths Bitters becomes extremely angry and upset over their loss, with Jensen, Palomo, and Smith mourning as well. Despite the "loss", Kimball leads the rebels to Armonia for one final confrontation with the Feds.
