Ben felt his heart beat a little quicker when Arvo had told him he was a sweet person. It was nice to be praised by someone. All he usually got in the ways of acknowledgment for what he had done was Kenny yelling at him while the rest of the group gave him a slight cold shoulder, and Clementine comforted him afterwards. Never once had someone called him a sweet person. So, this was different, and not unwelcome. 

After a while, Ben had just sat with Arvo, saying nothing. Then Clementine had come back in the house with an excited Kenny and he wondered what was happening because he hadn't seen Kenny actually excited since they had gotten that train to work what seemed like a million years ago. 
Apparently, Kenny had gotten a truck to start and he said they would be going to a town (Welington? If Ben had heard correctly) soon, then the subject of Arvo came up. 

Kenny, of course wanted to leave him and Mike and Bonnie were arguing for him to come with them. Kenny wasn't hearing it. It seemed that they were going to start fighting and Ben wanted to start in. Of course Arvo was coming with them, he thought, Ben knew on some level that being separated from Arvo would destroy him. 
He had already lost so much, he didn't want to lose Arvo too, and then he silently made the decision that if Arvo had to stay behind, he would stay with him. He had no ties to this group, other than Clementine. 
That's when Arvo had spoken up, asking if he had a say in any of this. Ben held his breath. 

"No, you don't cus' you ain't comin'." Kenny said with irritation in his voice, he seemed to be a bit more calmed down now, now that he had eaten and gotten a truck working and all didn't seem completely hopeless. 
Bonnie sighed then and looked at him, "of course you do." She said, giving him a look that said 'go on,' even though Kenny made an exasperated groaning sound.
