South's eyes widen; he doesn't need to say anything else, the realisation settles into her features barely a second after the two words are out of his mouth.

Maybe they never really talk, but what they have shared has told her more than enough, and words don't say as much about what Rune means to Brand as the way he acts with him. Around the rig, in the memory she saw...

"Oh. Oh fuck. Like— disappeared gone? Are you sure?"

She asks, but she gets the feeling he is. That he wouldn't be this messed up, hiding in a goddamned corner, if he wasn't certain Rune wasn't here, because if what she's seen is anything to go by, if he thought Rune was somewhere else and in reach, he'd be out there trying to find him.

That maybe he knows in whatever way he knew that Rune was having a nightmare all the way in another room, in that memory of his.
