Crossing between celestial borders, he can feel the heavy, heavy weight of humanity and wolf splinter off piece by piece and become something more. Something bigger and something less.
There is a golden aura shining all around. It is warm and familiar, soft and strong.
The heady smells of damp earth and autumn wind fill the air, surrounding and embracing him.
He had come here with Nymphadora ("'Tonks!'"). Somewhere near him he can feel her smile. She is smiling, fondly, the way one only can in the clarity that death brings, because she knows. She understands that he does not belong to her, nor she to him.
He had loved her in his heart, truly. However, that love could never quite intertwine with his soul in the same way that it had with Sirius. Even after Azkaban, even after he was lost to the veil, that love had remained as vast as the universe and ever expanding.
"Always… Always, Moony… Always…"
She leaves to continue on as the gold that is Sirius entangles him and two become whole again.
