At first, he was angry. Reasonably so. He left without saying anything to anyone, just wanted to get as far away from the Unit as possible.
It was only after he reached the nearest orange-zone town did he wonder why he didn't just go to the Deathzone? He was sure that damn Uncle would react in some way and get him back again.
But Ron entered a coffee shop to have a meal, a cup, and time to think about stuff, and realized entering the Deathzone was a stupid thing to do. He would just look desperate and childish, proving Agni's point. Besides, even if the berserker picked him up again, he would probably strap Ron inside the logistic truck heading to this city.
Nothing would change, really.
