Shortly before Benjamin's assault on Room 1004, Tserriednich drills Zetsu with Salkov in the master bedroom, secretly practicing his ability at the same time — Salkov does not know.

Theta walks straight past him, and he lowers his gun, savoring the pleasure of being ignored — then heads out on his adventure alone.
