Julia prepares to address the men, but Allen Jr. interrupts her and takes credit for the victory, claiming that he left to find her and that the retreat saved their soldiers from becoming prisoners. Though their men are skeptical, Julia then "agrees" and calls him a genius, convincing them of Allen Jr.'s claims As they celebrate, Jr. lifts Julia up in front of them and asks to share a shower with him, to which Julia responds by slapping him on his cheek.
Julia accompanies Dolores in driving off attack from the Regular Army.
