Summary
"There’s a second chain, attached to his other self’s collar. It’s as thick as the one holding the Puzzle, shiny and new, gleaming under the sunlight pouring in through Yuugi’s skylight. The chain trails, long enough that it lays slack around the legs of Yuugi’s desk chair, at his other self’s feet, and slinks up to wrap loosely around Yuugi’s hand.
He doesn’t think his other self can see it."
