The next day after the Pain Games, Millie tries to comfort Moxxie after he failed every event. When Moxxie begins to tear up, Millie suggests that he leaves to get cleaned up.

Millie quickly receives cheers and praise of the campers with her skills in volleyball. Millie participates in several physical activities, each one she completely succeeds at, and becomes increasingly popular online as a camper streamed her. She sings about how she is just a Regular Joe.

Millie meets Moxxie behind the cabins and is joyed about having people cheer for her, but Moxxie reminds her that they still have a job to do. Millie then wants to kill the target she suggested earlier, but Moxxie states he has to do the job right, which Millie concedes to, and gives him the idea to win over the campers with something he's good at. Millie tries helping Moxxie at the campfire where he ends up singing a horrible campfire song, which creeps out the other campers, however Millie ends up upstaging him with her banjo playing, causing Moxxie to run off crying.
