"His initials?" Cricket has to consider that seriously, something sober and a little sad creeping into his expression. "...nah, not that. I'm not sure how he'd feel about it."

It sounds too much like a token exchanged between lovers, and Cricket is pretty keenly aware Jack's brain didn't work that way where he was concerned. He smiles again a moment later, though, and asks tentatively, "Can you engrave 'invincible' on it? The word? Or is it too long?"

"See, there was this story about Jack and his brothers goin' around in Franklin, about how they couldn't die. And that'd be a good way to remember him, and maybe good luck for me, too."
