Team Bondi's amazing animation was on full display here, actually succeeding in turning facial animations into gameplay. When you ask people questions, they'll react in a certain way. Sometimes it's obvious that they're lying, since they won't look you in the eye after their response. Other times, you might just notice a subtle tic that tips you off. You'll have to read their voices and expressions in order to figure out where they stand. Are they trying to hide something? Or are they just deeply saddened by the news of the murder?

That should answer your fears.
