Albus was about to protest and say that Rose was probaly fine, but he was soon being dragged along the corridor by his friend. He was sure she was fine. She just took ages to get changed sometimes, what with being a girl and checking her hair was still perfect and all.
"Hey, slow down Scorpius" Albus protested.
Rose had foolishly left her wand back in the compartment too so when she went to unlock the door, Alohamora would have worked if only she'd remembered her wand. She laughed for a moment thinking she was being ditzy not being able to open the door, but it was true the lock was sealed.
Mia watched the handle rattle and sniggered to herself. She then heard Rose banging on the door and calling for help so she muttered a curse to silence the room.
"Much better" Mia said when the calls were now unaudioable to her or anyone passing.
