When would Zack-kun have slept in here? Did he not become a shade like most of the others, and he was here during the time we believed he had died?

[Makima uses all her femme fatale energy to lean over the bed without further disturbing it. Is there anything she can deduce like the outline on the bed? Order that the figures were present - is the idea that Zack just stank up the entire room and Thing 2 occupied the bed? Both in the bed? Attributes of the other person - human, godlike, maybe male or female?]
