Raito lapsed into silence as another change of floor number came about - they had be getting close to the bottom, hadn't they? And even if he was walking behind Schuldig, he'd feel much better in his own room -- which was... on the way.
No one was supposed to know where his room was. Looked like he'd have to make up an alibi for leaving the building or keep going to the cafe - both options not exactly appreciated by Kira, who really only wanted a chance to tend to the ache on his face. It was distracting.
