I also have this headcanon that when Raleigh saw Newt’s tattoos, he thought they were memorial tattoos at first. He’s all soft voiced and kind when he asks if it’s a tattoo of Yamarashi - he and Yancy took out Yamarashi, but that doesn’t mean there weren’t casualties. Raleigh saw the destruction first hand and knows that they couldn’t have saved everybody (and you know the guilt eats him up inside, especially after Yancy’s death, because that’s one more failure). So he’s reaching out - I’m sorry for your loss, I know how you must feel, I was there, but at least we got the bastard.
And then Newt is so casual about it. Twenty-five hundred tons of awesome. And Raleigh sees that his sympathy is misplaced. That this guy is so far from getting it, he might as well be on another planet. Or more specifically, from the safe zone for the rich and powerful (because how else would he end up being so blase about the giant monsters who’ve been attacking the most populous region of the world for over a decade?). And Raleigh is already done with this privileged man-child.
