[Stark decides it's time for some mental math. So, let's see here: the guy carries and obviously doesn't mind a fight. He instantly has to verify whether or not he means real monsters or figurative ones. Now he's like a hound with a scent about just how not human Stark might be. He's asking questions first instead of shooting, but that's not enough for Stark to assume he doesn't just blindly make anything not-human his business forever and frankly, he doesn't need someone looming over his shoulder.]

[That's how people lose an eye or two.]

Judging by the fact that you're asking at all and it's apparently so damn important to you, it's safe enough for me to say that I'm probably on your side.

And that's all you need to know.

[Stark knows he already knows he's not all the way human at the very least. There's no sense in hiding that. But he's not broadcasting that he's nephilim. It's not something that he wants to be. So not saying it somehow magically makes it less true for him and he's good with that.]

[It's also just generally not any of Dean's goddamn business.]
