He had expected a hornet's nest, certainly. Not quite this, though. 

The hammer thudded hard and solid into Keystone's chest, pushing with sheer force. While he retained his stance, the pugilist made elongated footprints as he slid backwards. The Dwarf meant business; his business mixed with the fury of a patriarch defending his own. 

Keystone adopted a low, defensive stance, keeping his hands empty and open. "I ain't fightin' you, Avar. I told you what was what, first night in. Your girl's the only one has any control on this, what I can trust just now. And [i]she already knew[/i], Avar, before I asked." 

It was a calculated guess, Saran had hinted so strongly that she was aware of what was happening. For all of her coyness, she knew a lot more than she let on. And Rocksteady, well... he didn't want to see it. But his protective instincts were undeniable, as was his strength. He'd do whatever he could to take care of his charge, well over contractual obligation or the value most men put on their word. Certainly Keystone's. The large man didn't want to fight his new friend, but his vicious attack may result in something outside of his control. Neither of them needed that. 

"You should come with us. D'you hear me, Avar Rocksteady of the Delzoun Clan? You should do this with us."
