Elan finds a jacket that the button belongs to, but all the buttons are intact. Katya says she traded a sister jacket a week ago. Elan remembers the customer was beautiful and First Class.

Logan tries to explain the reasoning to Till. She throat-punches him and they fight. One of his minions sneaks in and tries to garrote her, giving Logan the opportunity to try to kill himself with Cold. Till manages to disconnect the apparatus before he succeeds.
