Thalia shot from her seat as she heard the crash and raced for the exit, peering outside. "What on Earth are you doing there?!" She hissed at them in a hushed tone. "And can you maybe look where you're going! You might wake the entire damn school up!"

"Sorry." Will said carelessly.
Martin was behind him carrying a handful of pastries. "Want one?" the Hufflepuff offered.

(Ah crud. School is a butt)
Kiko, surprised by the noise, leaped onto Silents head. "What is it, Kiks?" She said groggily. "That was a loud noise.." The owl chirruped, notioning towards the exit. "Fine, we can go on a walk.."

Will pulled Martin away from Thalia and headed back down stairs. "Forget the astronomy tower. I'll see you tomorrow. He headed back into the Slytherin common room and sat down on the couch, practicing summoning birds. "Avis!" he cried, and three tiny birds appeared over his head.

She let out a sigh, "It's fine, can I?" She asked cautiously, slowly stretching her arm out, before pulling it back. She glanced at him, a slight frown on her face. "Bye?"

Silent heard the spell, and peeked in curiously. Don't wreck his concentration... she thought. Kiko, however, had other plans and flew eagerly towards the tiny birds

"What the?" Will exclaimed, seeing the tiny owlet among his finches. The finches disappeared in a puff of feathers. "Oh bugger it." he groaned, brushing feathers off his navy blue dressing gown.

"S-sorry.. he just did that suddenly." Silent appologized, scooping up Kiko

Will sighed. "Avis." he said. The three finches resumed their previous existence.

Be polite, don't just walk off. Try to start a conversation or something she thought
"W-William, was it?"
