Martin starts back as Ange reveals that the strange green fluid everywhere is blood. He can't imagine whoever the blood belonged to is still alive, which means there's a chance they're going to find a body somewhere too.

He reaches forward as though about to touch it to confirm and withdraws his hand again, recalling the warning.

"That's an awful lot of blood..." There's probably some hidden danger here somewhere then, which means they may be in danger too. "Looks like it's still pretty fresh too?"

He's not even going to touch the obvious question about why the blood is green. It can wait.

He takes a deep breath, trying to steady himself. "We'll have to be careful. Like. Really careful. Stay close, okay?"
