Clint came to the meeting, of course - any meeting that Mark called, something important was up, even if it was just about organizing daily work rosters for harvest. None of the communal gatherings have been pointless, a fact that he appreciates, and most of them haven't been for emergency situations, which he also appreciates. This one doesn't strike him as an emergency, but rather something they have to watch for, be wary of, and try and find some sort of reason for it.

It was entirely possible the Observers were just massive assholes.

But Clint's been on guard about this since he found Bev trying to destroy her own letter in their fireplace. He'd even offered to steal for her, but they were both in doubt about that being effective since Bev had gotten the orders. But here, now? He has a possible out for this place, or at least a way of finding more information. For that, he's willing to risk quite a lot. So when Lyanna finishes explaining about her letter, and the new conditions, he speaks up.

"If you - or anybody who got one of those letters - want to hurt someone to see what happens, you can hurt me. I'm willing to try just about anything to find a way home."
