Perhaps a mortal would not have felt the anger and irritation coming in waves off the human, but Ares did. He was, after all, sensitive to such emotions. They were easy to manipulate when he wished to stir up the blood lust and battle frenzy that drove troops to do what he wanted, which was slaughter in his name. Of course, he could also manipulate those same emotions to make people uncomfortable and do things they normally wouldn't. Like... oh... throw a fit in public.
But that could wait until later. Much better, were such a fit to occur somewhere with a larger audience. Besides, he was still enjoying the game. Especially since the other man didn't even know there was a game afoot yet. Or rather, didn't know that Ares was one of the players.
Now, the blond, that was something else. He couldn't help but wonder who he was. Or had been, since obviously he was someone else now.
Scooting his chair over, and letting it make a loud, obnoxious scraping noise across the floor, he pulled himself over to the table, shooting a grin at old sour puss, and reaching to his old table for the beer he'd been enjoying before he'd so rudely intruded. His eyes went back to the blond though, wishing he knew who he'd been. It would make it so much easier to poke and prod at him. "Yeah, guess I do. You get those feelings often? That deja vu stuff, I mean?"
