YES especially when he recovers from his nightmare-smeared, sleepless nights. He might wish to attempt an interrogation, either about the nature of that sleep, or if Pitch was somehow involved, and that's where the sedative fingers can come into play! Unless Pitch sees him for specifically therapy (Pitch could always be demanded to attend a session, by the government perhaps? Another authority?), I could have Chilton attempt interrogation at an otherwise social (but private!) event between them?
