From the Transfiguration corridor, Mo had followed the goblin to the Prefect's Bathroom, but once it disappeared inside... well. He couldn't follow it anymore, could he? Instead of waiting around up there (which would have been smart, now that he thought about it), Mo continued down through the school in hopes of running into SOMEONE who could tell him what was going on.

By the time he got to the Entrance Hall, Mo was kicking himself for not staying outside the Prefect's Bathroom. He wasn't doing a bit of good wandering around like a curious crup, and he'd probably lost the goblin completely now...

Oh, hello, another goblin. Mo slid to a stop, making eyes at the goblin with a sword facing off against two girls. "Oi. You." Think think think, Branxton. Use that Ravenclaw brain. "I want to speak to your leader."
