Analysis
Bateman is at the gym going through his usual routine. He enjoys the feel of his muscles burning. In his gym locker lie three vaginas he’s cut off women, one pinned with a barrette and a blue Hermès ribbon tied around his “favorite.”
Bateman is back to his typical regimen of exercise and shallow focus on his body, though he now has in his locker three souvenirs from his sadistic and sexual murders, which he treats like trophies.
