—Prologue—

It had been nineteen years. Nineteen years of waiting for her to be lulled into security, despite the Doctor's warning. "I didn't find a body. Keep a constant vigilance! ... And bow-ties for your husband. Bow-ties are cool. Geronimo, The Doctor." The woman had left the note lying on her potions desk at home on Spinner's End, waiting for anyone to read it. And for anyone to smirk at it. Which is what he had done. Foolish girl. Foolish human. After all, his pet name for her was "Silly" for a reason.

Naturally, as all humans did after time, she allowed herself to...forget about him. Forget about him being a threat. He'd make sure she'd live to regret that decision. However, dare he say, clever of him to let her forget about it. Let her grow used to the feeling of safety before ripping it brutally away from her. Nineteen years of lying in wait were going to pay off now, he could feel it in his head. For her, he'd even undergone a regeneration so he wouldn't be recognized while he stalked her under a stolen Invisibility Cloak, just in case the cloak fell off. Now, today, he'd let the Cloak fall and take what he wanted in front of her dear husband.

His icy blond hair had grown into thick waves of pirate-flag black hair with scorching auburn eyes underneath his bangs. To throw her off even more, the Master had also grown taller, and more natural muscle had been added to his frame. Not too much to make him look abnormal, but just enough to give him a perfect body without trying. Oddly, that was exactly what the Master thought of when the regeneration started. He shook his head, wondering and took a seat in front of Silwen's potions shop, waiting for her and her and Draco to return, having come back sooner than they.

Today, the happy family had dropped their son Scorpius off at the train station for his first year at Hogwarts. The Master had watched as Silwen kissed Scorpius good-bye, watch her take her idiotic husband's hand and caress her pregnant stomach with a tender look in her eyes. Absolutely nauseating. He'd whip that out of her, starting from day one.
