"Heartbeat's rising, Stiles," Theo says, casually, causing Stiles to grind his teeth together in aggravation at the reminder. Theo can know so much that Stiles is only left able to flounder a guess at.
"But its not because you're afraid... no, the nogitsune is gone. But you've still got more blood on your hands than any of us," Theo provokes, Stiles knows it - it has to be; there could not - he couldn't think of any alternate purpose to any of this, the words that tumble forth.
Stiles is a murderer. In fact, he's murdered the most. (Even if that number's only one, and it ties with Theo; still, its the most.) Who is he to pass judgement? And yet, his hackles rise, anyway - who is Theo to say that? What does he know, and anyway, how does Stiles know Theo isn't still lying through his teeth? Stiles has murdered... numerous people, if you count the nogitsune's killings, using Stiles' mind and body to commit them - people have died because of Stiles, right? - so, yes, he does count that. So, if you count that, how does Stiles know, how could he know, whether or not Theo has killed more people?
"I'm about to get more," he responds, darkly, watching Theo's face to try and catalogue even the most micro of expressions that might flicker across those too-handsome too-perfect features of his.
As per usual, he unable to read anything. His rising heartbeat is not fear, as Theo so rightly deduced - but anger. Adrenaline.
Stiles punches Theo in the face. It's unsatisfying; he only stumbles, half bent over, staggering off to the side. Theo doesn't take all that much time to recover, a horrible grin stretching his mouth wide. "There he us!" He shouts, half-delighted, half-manaical. The disguise has fallen. Stiles, maybe for the first time, is seeing Theo Raeken, the man, the person he has become since ten years ago when his sister died and he left town - the last time Stiles had ever truly known him.
"That's void Stiles," Theo proclaims, almost proudly, and it sends his skin crawling. Ants running up and down his extremities, and he can't help it, when Theo continues with "It felt good, didn't it?" - Stiles has to punch him again for that (because it did, yes, feel good, and he refuses to admit it in so many words, but Stiles was always one for the practical demonstration of things anyway) and this time, this time, thank god, Theo falls down like a sack of bricks, ending up splayed on his back on the hard tarmac below.
