The way he remembered it, the fish, or whatever, that they had seen seemed to be... glowing.
He could have asked Milo to confirm, since Milo had seen it too, but a part of him was scared to. If Milo confirmed it, then that would have meant they had both seen it that way. And that would have meant that, in the middle of the back woods at night, they'd encountered a glowing flying fish just making its way through the trees.
