Predators are always killers if given the right prey. It's just a matter of time. Adam has been prey too much in his life to believe what Derek just told him. To Adam it's almost laughable, except that Adam isn't the sort of boy who laughs all that often. He isn't the sort of boy to even smile all that often, or to let himself be happy. What's given can be taken away, even emotions.

What he saw in his dreams looked like a monster. There were flashes of images without any context to Derek's story, or to any story really, just images, disjointed and unclear. It was violent and bloody and also kind of sad. Derek was chained up a lot. Restrained. Why restrain someone who isn't dangerous?

"No one has their... whatever powers they had here." Meaning, that's why Derek isn't dangerous right now, at least to Adam. And even then, the anger he'd seen in Derek's eyes in those flashes in some places, Derek could probably still be dangerous. Adam's predator was a human, after all. Nothing spectacular about Robert Parrish.

The knowledge that Derek saw any of Adam's horrible messed up life back home, the knowledge that Derek knows how weak Adam has been and sometimes still is, it's upsetting. Especially if Derek is as scary as Adam saw. He nods at Derek and stands up again. "Deal." Best to just back slowly away and pretend it didn't happen. "I'm good at keeping secrets. Just don't come after me an Ronan. That's all." Because if that happens, all bets are off. Everyone will know about it. Adam will scream it from the mountaintops, so to speak. Self-preservation at its finest. That's one thing Adam is good at, self-preservation.
