She heard that the Kitchens were open. OPEN!

And upon hearing that, her mind immediately flew to Kurumi, the Gryffindor Prefect who promised to teach her how to bake cookies last term. She was very excited at the prospect of it and when she had the chance--that was when classes was over, she headed out to the places where she might find the lioness. She explored the grounds yet didn't find her.

So, she decided to check in the Kitchen. Maybe the Prefect was way ahead of her and was already there.

And sure enough, she was not mistaken for when she took a peek at the Kitchen, the Fifth year was there indeed! "Kurumi! Haiiii..." she greeted. "I've been looking all over for you."
