So, what is Estes' deal, anyway? He is on board with the hunt for Dante, and is demanding the quarantine of talkers. He also has deemed himself "judge" in this society. And he is skulking around Sun Mei, asking about her research trying to discover the difference in brain chemistry between the conscious, talker Zs and pure zombies. Which she is being cagey about. Definite sketch vibes coming off of Estes, and rattling Sun Mei.
