Jarek has been quiet for some time, trying to learn whatever he can from watching the experienced duo at work. His normal response to encountering small children like Peace is to volunteer himself as monkeybars, but that didn't really fit the "worried brother bending the rules" persona that he was trying to project, so he said nothing unless it was to agree with the others or answer a question as briefly as possible.

But now they were perhaps being spied on themselves, which wasn't that different from being stalked by a predator, and Jarek knew a thing or six about predator behaviours.
"If she's trying to spy on us, she'll have to keep following us wherever we go, or guess where we're headed next and lie in wait. It's always easier to ambush than chase in the open. So--not to contradict, Glen, but--maybe we should just keep walking for a while and see if we see her again? Or two of us keep going and one of us splits off to spy, and we see if that makes her nervous. If we're really lucky, maybe she'll get spooked and our spy can follow her back to her den--uh, her safehouse, or whoever she's reporting to, I mean. I don't know if we can afford to jump at every shadow; we're not antelopes."
Jarek pauses and stares at the wall, realising his predator-prey analogy is running into trouble in his head. Jumping at every shadow is exactly what prey does, because it can't afford not to. This is like a predator stalking a predator? No, they want her to not think they're prey. Because... prey for a spy is another spy, and an ordinary citizen is another predator: boring unless they're in the way.
