[Arthur...]

His heart is in the words, all of them, no matter how intense. Perhaps especially in such a case.

[There is no one on this boat who knows how much of a vicious fuck I can be. Which is why I promise you, Arthur:

I will do everything I can to stay alive, to not go back to the dark world. But if there's no way out? If there's no hope at all?

I will make sure to take you with me. ]

And he knows, knows, Arthur will understand the love in that promise. Because he, John, would hate that. But for Arthur, he will.
