Maybe Leo and Ares would be drinking buddies at the tavern, considering how they're close in age and have both seen a lot of combat? That's the sort of thing that binds men and although they may not have fought together, they have a good guess of what each of them has gone through. Ares would definitely buy Leo a beer and give him a pat on the back, and if nothing else, he'd just enjoy the man's company in silence.<br/><br/>I suppose that apart from a dark sort of aura around Ares (which is more visible through the way he acts and behaves than an actual aura), it'd be hard to tell that he has anything to do with magic.
