The last time he'd been in the presence of the rose, Tom had been exhausted and ill. He had not been able to hear the song, to feel the vibrations that had affected River and Anthy so. Black 13 had clouded his senses with darkness so cloying he thought it would never lift. Nor did he wish it to do so.
To my surprise, and my delight, I saw sunrise, I saw sunlight
There are places in which Tom feels most contented - the meadow in London Below where the family goes flying, the family rooms in the House of Arch, their cottage in Brittany. He fits in those places. He feels utterly himself there, and utterly loved, faults and all.
I am nothing in the dark and the clouds burst to show daylight
He closed his eyes in the last moments of stepping through his door, in fear, partly, of opening them and feeling the dizziness, the ache in his head, the repulsion he'd experienced during his first visit. When he opens them-
The sun will shine on this heart of mine
There is a rose. It is just a rose. Dusky red and full-petaled, like the ones in his favorite courtyard, but so much more.
And I realise cannot live without, come apart without it
He knows he fits here. He knows in the core of his being that he has come out on the other side, and, finally, he hears the song.
At full tilt, and in full flight, defeat darkness, breaking daylight
He hears the voices of those he loves in the song. The vibrations, the humming tingles up and down his spine, and he feels the magic, the doorways around him, the unlimited possibilities. He stands, as once before, between a gunslinger and a girl before the rose, and this time...
Slowly breaking through at daylight
Oh, this time...
Slowly breaking through at daylight
"I didn't know. I never- I didn't- It's so..."
Slowly breaking through at daylight
Tom Marvolo Riddle, Lord Ostium of the House of Arch, smiles, struck dumb with joy.
