A reasonable deduction, but I admit, I expected better from X.
The real truth here, is that the keyholes in Mami's old-timey wooden furniture were a means through which Schadenfreude expressed itself upon the world; when Kyoko destroyed the furniture, the abnormality's presence in the collective unconscious became tenuous, and it was easily dispatched.
Clearly, this is what Binah, in her infinite wisdom, meant when she said that "people should not make an eye contact with the drawer".

Seems legit.
We should tell this to Kyoko, surely this would make her mood better, there is absolutely no chances that she would look at us as if we had grown a second head when we do.
