At the end of S2E2 of Evil, Kristen, David, and Ben go to the house of the man who claimed that he was possessed by an angel, searching for his wife, Ashley. When they arrive, he seems to assert that she has been turned into a pile of salt, which the camera then pans to.
Obviously, the most obvious hypothesis is that she was in fact turned into salt, but that seems rather egregiously supernatural for a show where virtually every case has been somewhat open to a mundane (or at most, slightly science-fictional) explanation. However, no alternative hypothesis is proposed by any member of the team. If the implication is that her husband killed her and somehow buried her in the salt, there is no way that she could fit, and there would be blood everywhere. If she simply disappeared and her husband brought a pile of salt into the house or something of the sort, it would seem odd for none of the characters to remark on this possibility or investigate it further.
So what actually happened to Ashley?
