A/N The only picture I could find of Rose Leslie as Molly is as Molly II.

Molly Prewett walked slyly towards the dungeons, staying out the way of prefects and teachers. In her imperiused form, she wrote down the Gryffindor's password. She managed to get to the Potions classroom, before a cry of "Petrificus Totalus!" alarmed her, and before she knew it, she was frozen solid.

Out from the shadows, a slender figure appeared. Since Molly was in a frozen state, she snatched the piece of paper inside Molly's hand, pocketed it, and then yanked some of Molly's red hair and dropped it in the cauldron.

Molly whimpered, wondering what was going on. She laughed maliciously and pushed Molly into her own personal dungeon. "Obliviate," she whispered. She mixed the cauldron with a large spoon and poured a cupful into a glass. She quickly drank it, unfazed by the awful taste like she had done this before.

She shrunk two inches shorter, and her luscious, waist length raven hair transformed into shoulder length curly, dark red hair. She changed into Molly's Gryffindor robes, leaving the frozen Molly with Slytherin robes beside her, her bra and panties clearly visible, making the Prewett bright red.

She chucked Molly into a broom cupboard with a lock that could only be unlocked from the inside and dressed Molly into the Slytherin robes beside her.

She apparated to the Gryffindor tower with ease, and said the password Molly had wrote down to the Fat Lady. She got in and rushed into Molly's dorm, changed, and climbed into bed. A couple of mumbles came out of the seemingly peaceful darkness, making her tense up, but then it soon faded away into loud snores.

She grinned, rolling over to the other side, whispering, "Hogwarts, be prepared."

"Danger is on your way,"
