Jane though of a way to incorporate the whole investigation squad on how to interrogate a prisoner. And everyone can get hands on experience.
Kindof base on Jane's preview where she has a POV interrogation.
Jane's preview with the pov interrogation all bound and gagged was chef's kiss. So we can imagine yourself or whoever is sitting tied up in that chair
Though I did this before Burnice was shown in the story so she's not the type to get tied up.
