Severus Snape.

Severus Snape had come to the Leaky Cauldron for a drink. The stress of his position was getting to him, really. I have to have an entire DADA curriculum ready, make sure Draco doesn't kill himself, make plans to ensure Dumbledore's ****, and let's see.... make sure neither side kills me. Why did I sign up for this? He took a swig of firewhiskey.

Lily. His greatest regret. One sentence, said 20 years ago. Now she was gone, left only in his memory and the eyes of the boy. Another swig. That stupid boy. Out of her fiery hair, perfect face, legendary temper, and the giggle he fell in love with, her son had to take after his Father. The face of his school bully, staring at him with the eyes of the love of his life. A cruel cosmic joke. Another swig. A jingle, the door opening. Who is this girl? Asking for a room at this time of night?

When Harry looked around the Leaky Cauldron, Snape took a glance. Piercing green eyes. Lily's face and expressions. Ill-fitting muggle clothes? His curiosity piqued, he got up and asked:

"Can I help you with that?"

She continued walking a few steps before Snape tapped her shoulder. "Miss?"

She froze. What does he want? "I'm fine." Is everyone going to hit on me in this body?

"Could I speak to you in private?" Snape asked nervously.
