It seems odd for a completely clean pestle to be left behind, doesn't it? I don't know, guys, it seems to me the mortar and pestle may be a way to point fingers at a certain person, someone we saw crushing herbs and doing stuff in the infirmary.

Given the mandrake root, he'd be the prime suspect. Would the killer try to reinforce that by leaving a mortar and pestle behind?

And if you think it was an accident, then consider this: wouldn't it be too convenient that both a mortar and a pestle fell down from Zaberisk-san's pocket or something?
