"Open the damn door woman.”
–Rachel and Red Harlow
The player can presumably interact with Rachel in the saloon between missions (the showgirl in the blue outfit is Rachel). She is also seen in mission Bar Fight seen running around the saloon and needs to be protected by player. After Red defeats the brawlers, she gives him his guns back and lets into the backroom to fight Dan and Sam.
In Battle Royale, she can be interacted with, and expresses her support for Red's victory.
