"Because they probably have it coming," Ben said seriously, half shrugging, "but it doesn't mean you should do it, man." Again, he didn't want to lose anyone, so he'd do what he had to to calm Castiel down.
Taking a big breath, Ben squared his shoulders and looked Castiel straight in the eye. "Ruby and Uncle Sam have been having sex at the house. Maybe even since Uncle Sam dumped Heather. Maybe before. Dude, they're doing it at the house where you can't see it, hiding it, and that's just wrong."
His smaller grip tightened on Castiel, as though a barely ten year old boy had the force necessary to restrain an angel. "But you can't go smiting Uncle Sam, because if you do, everyone's going to be pissed – epicly pissed – and you're supposed to protect all of us, but you can't do that if everybody's trying to kill you back."
It made perfect sense in Ben's mind, it would just be a huge mess of people killing people in revenge for more killings and if Castiel didn't smite anyone, none of that would get started.
"So you can kick Uncle Sam's ass like humans do and yell at Ruby and- here-" he let go with one hand, picking up the baseball bat, which he held out to Castiel, "and hit walls and beak things, but no smiting because you're better than that, Cas. If Ruby and Uncle Sam want to have sex, there are other hot chicks in LA. Lots of them. You can do so much better than her. Just ask Dad, he'd say the same."
