Ben was taken by surprise when Arvo hugged him, but when he did something seemed to stir inside him, nerves or [i]something else[/i] but he decided to put it in the back of his mind, an issue to deal with later. 
When the other started apologizing he shook his head, "N-No it's...That was fine." He said, mentally smacking himself at his awkward phrasing.
"Let's uh...Let's sit, so we don't draw attention." He said, taking insinuative and sitting down him, motioning Arvo to join him. 
When he had they were silent for a few moment, before Ben said, "I'm sorry...For how Kenny's treating you." He felt like he needed to apologize, even if he was not at fault he couldn't help but feel guilty, maybe if he had let Arvo run away when they first met like he had thought about, Arvo wouldn't be in this position, this was all so fucked up and he couldn't but feel like he was to blame.
