If Cas cares at all that Dean is flirting with the waitress, it doesn't show on his face. Honestly he would be more shocked if Dean didn't flirt with the waitress. It's just...Dean behavior. Cas just eats his plate of meat (eggs, sausage, bacon and hamsteak, seriously Cas, at least there was toast involved) and calmly stares out the window as he chews, watching the cars idle by. Vegas isn't too bustling in the morning, is it? Still hot as hell, though.

Cas makes a pleased sound when Dean picks up a new phone, and makes him program the number into his own cell. Finally, a line of communication for if they get separated, although God willing that won't happen again. At least Cas can feel when there's a Leviathan nearby now, two beads of Grace humming like miniature generators, waiting to be reunited with the others.

They're on their way toward a video rental store when Cas's hand snaps out and grabs Dean's upper arm. "Stop the car."
