Dean considered things a little bit, looking at the phone then back at the angel, strangely reminded of the first few times Castiel had tried to talk to him and busted a television and made a radio go haywire. It was almost amusing how easier Duma seemed to be going with the electronics. "Well...if you ever wanna talk about it, I'm all ears." It was probably pretty interesting, had to be more than what he'd heard about other angels. Anna had been about the only one sort of interesting...and even she had turned out to be a dick who just wanted him dead.
Once Duma finished up his burger, Dean gave a smile, looking up from the food to make sure everything else was on the table and good to go before sitting down. He grabbed a napkin from the little holder on the table and raised a brow at Duma not actually doing anything before remembering that he was an angel, right, and well if he didn't have a body like Cas...things were probably really different in what he knew. "So... this...guy. Body. A vessel or were you born looking like this?" He reached out for Duma's can, holding it up a little so he could watch him pull the tab and open it before turning it around to him. He hoped that and picking up his own burger for a bite would be good enough.
