What's going on? Jackson wonders, knowing Jono will hear his emphatic question. It's the 'by now' that makes him wonder, the idea that ... that this has happened before scares the hell out of him. How could he not know something like that? Why didn't Jono tell him?

"I'm not going back," Jackson states with a note of finality, stepping forward rather than back. John Hart doesn't scare him the way the feds do, even if he is their messenger. "You're outside your jurisdiction, Agent. You can't police the Nexus and you sure as hell can't police this universe."
