Buck stops Ando and Hiro at the entrance to the psychiatric hospital. He thanks Ando for checking Hiro in, and tells him that non-patients are not allowed past this point. He takes Hiro into the cells corridor, and when Hiro points out "Dr. Watson's" cell to Ando, Buck drags Hiro away.
Buck is pushing a cart of medicine through a room in the asylum. He sees Ando touching the cart and warns him not to mess around with the medicine. Ando claims he was just observing the cart. Buck realizes Ando is Hiro's friend and tries to shake his hand, but pulls away after Ando sneezes in it.
- After Buck introduces himself to Ando, Ando introduces himself as "Chuck". Chuck & Buck is a 2000 film.
