Harry started awake, his hand slapping over his buzzing wand to turn it off. He checked that the silencing charms he'd put up last night had held and then reinforced them anyway. He put on his dressing gown and his warmest socks, then proceeded to shove conjured pillows under his blankets in the vague shape of a person, just in case.

Harry knew it was a bit mad.

He just... he just needed to know.

Once he knew, then everything would be fine. He was certain of it.

Harry pulled on his invisibility cloak and carefully cast silencing charms over himself. It was just barely dawn when Harry stepped out into their tower room, wincing at the cold floor and taking a deep breath of air that smelled like frost. He tugged the curtains closed behind him and tiptoed to the bathroom, easing the door open and then shut again, holding his breath and wincing at every little sound.

The bathroom was small. Harry pressed his back against the wall, behind where the door opened and took out his wand. He'd practised for nearly two hours and pretty much had the knack of it now.

"Notice me not," he murmured, focusing only the half circle he stood in. Then he cast a warming charm on himself and softening spell under his feet before pulling his robe and cloak more tightly around himself to wait. Draco would be up in about an hour.
