Recced because: It was livii who sold me on the pairing of Harry Sullivan and Martha Jones and she's the chief advocate of the pairing. In this lovely missing scene fic we see that Martha has discovered in Harry Sullivan a man whom she can trust and love.
Harry takes her in his arms, ignoring the looks he earns from the people around them.
"Martha," he says gently, "Doctor Martha Jones, you've studied, you've worked, you've walked the Earth and you are the doctor now, you know. The definitive article, as it were, to me."
She smiles at that, real joy lighting up her eyes. "You keep saving me, Doctor Sullivan," she says, laughing as he furrows his brow in confusion. "I love you."
He kisses her and she remembers touching all the stars in the sky.
