So...so high up.

Upon reaching the last step in the long flight of stairs that she had to conquer on her way to the Astronomy tower, Cass leaned against the wall for a minute to catch her breath and glared at the old set of stairs, as if it was its personal fault that she had to climb up so high.

So, when she finally caught her breath, the blonde Slytherin walked into the barely occupied classroom and smiled, good. She was early, she liked being early. Especially to classes that were miles and miles away from her own common room.

"Good day Professor..?" She trailed off, realizing that she didn't know who the woman was, and didn't have any way to find out. But nonetheless, she smiled at the unfamiliar woman before glancing at the instructions and doing so.

After scribbling her name down onto the seat plan, the girl grabbed a bottle of cola and a plastic cup, just as instructed then walked over to her self assigned seat where she poured herself a glass and began to sip, patiently waiting for class to start.
