[There are only three situations that allow him to fall into a deep sleep outside of injury or medication. Ichiru is not here anymore and dead back home--no chance of that unless he returned. Yuuki sitting in his bed patting his head--he's not that child anymore and she's not that little human girl that took away his nightmares. The third one was--the stables at Kurosu Academy. Specifically in Lily's stall where she would often lay down with him and comfort him as he experienced the more severe bloodlust episodes. Even if it terrified the rest of the horses. None of those were options here--at least not since Ichiru had left.]
