"That's what we thought last time." He shakes his head, and picks up the bottle for another drink, feeling far too cynical for the hope that has been offered to them. It should be rather straightforward in practice, but the risk of something going wrong seems so unfathomably high. Even just one mistake, one stone that does not make it to the present day, means this plan will probably fail. Doubly so if it's Time that does not return with them.

This is a different danger than Thor is used to facing. He's been in countless battles and been wounded in combat, and been left for dead. And he'd always faced them with the same courage and bravado, assured that even if he did not come home, his soul would find its place in Valhalla. But this is something else entirely. There will be no mortal danger to him on Asgard, his home for hundreds of years. The greatest threat to himself comes from within, now.

He doesn't know what will come of this. Whether they will succeed or fail, or if it will even solve anything, in the end. But he's learned how uncertain life is, how quickly things can change, even for long-lived Asgardians, and he cannot assume that this will end as they wish. "If something should happen to me," he begins, hesitant but steady, looking out over the grassy yard, "I want my boat burned in the waters off Asvera."
