John almost defends the choice he's made, almost tries to explain to Karen that Brady would have shot her, but in the end he doesn't. All along, from the moment he had arrived in Darrow, Karen had trusted him, and he trusts her now. Trusts her to understand his choices, why he'd shot for centre mass instead of the kneecap.

But whether or not they're the right reasons, he trusts Karen to know why they exist.

He nods once and says, "His connection to the Rambaldis will be uncovered before long. If he disappears, the police are more likely to blame their operation for it."
