I have a theory—Perry is an undercover agent. He freaked when he killed Eryn, probably because he’s not supposed to kill. It might’ve just been him panicking as she ran away. It could also explain why he’s trying to stop them from killing Jayson over this mess-up. We know McGinty called someone.

Yes, the controller might have been doing 2 positions, but that doesn't prove that was the fault of the accident.
