It's Cat's first day at Hogwarts and it's filled with stern teachers, avoiding the other 7th year girls, and an awkward run in with an extremely hot guy...

Cat and Sirius duel it out in front of the entire class! Also, there's a little run in with a love potion!!

I turned to face Remus and James with an evil grin on my face. “What are you up to?” James asked, eyeing me suspiciously.
“That love potion isn’t going to be for McGonagall, is it?” Remus asked, equally suspicious.
I shook my head. “It’s for Sirius.”

I shook my head and buried my face in his chest. “I have to go for extra help on Saturday morning. We can’t go to Hogsmeade together.”
“Yes we can. I can hang out with my friends in the morning, then meet you here when you’re done. Ok?” I nodded. “Good. Do you want to go play some Quidditch before dinner?”
I smirked. Icarus could beat me in Charms, but I could cream him in Quidditch. This was just the distraction I needed, I could always count on him to be my bandage. “Of course!”

“Um, Cat?” He sounded perfectly confused.
“Hm?”
“What are you doing?”
I pulled his shirt off and tossed it under a bush, grinning at the way the filtered sunlight reflected off his chest. “I figured we should do something that would really get us both wet, just to amuse Ben.”
