"Hey, I'm not --" Ray winces, reaching out a hand on instinct, but drawing it back as soon as he realizes that even a friendly gesture like trying to touch his shoulder might make Danny bolt, at this point.

"I don't think you're a freak. And the fact that this upsets you ... that alone proves you're not an emotionless monster, wouldn'cha say? It doesn't matter to me what you are - ghost, human, both - you're still my friend, okay? And ... I'm not gonna let you wall me out like this. Not when there's a chance I might be able to help you. Even if it's only by bein' around when you need me."

He holds out one hand, hopefully. Maybe a handshake will do, rather than the hug he really wants to give him.
