AN: This idea just popped into my head…I'm not sure why.

As Lily grew older, it became clear to Harry that she somehow inherited a mutated form of Ginny's inherited Weasley temper. Actually, it came to Harry as an epiphany in the form of a letter from Hogwarts.

Lily walked down the corridors of Hogwarts with the most recent love of her life, Brian, on her side. She wasn't protective of him. Even though his popularity jumped a few notches after winning the quidditch cup for Hufflepuff, she knew he was hers. If only other people saw that.

Brian stooped to tie his shoe. As Lily waited for his fingers to fumble over his laces, Tory decided to stop and talk to him. Obviously trying to make a move when he was at his most vulnerable.

"Hey, Brian. There's a Hogsmede weekend coming up," Tory flashed her eyes and flipped her "man grabbing" hair over her shoulder. "I was thinking you could help me better my flying skills and then we could grab a butterbeer later. What do you think?"

Brian looked up at her and looked over at Lily. His girlfriend's cheeks turned crimson, but as fast as the color came, it was gone. He felt his stomach drop.

"Excuse me," Lily put on her sweetest smile. "I know you're not trying to steal my boyfriend or anything, but it is certainly coming off that way. " Lily then reached into her pocket and flipped open a four-inch switchblade. "Touch my man, I will cut you."

"Where did she get a knife?" Harry wondered out loud as he read the letter for the fifth time.
