Now, we’re going through deception-themed monsters: wraith, shapeshifter, ghoul, even a shape-shifting demon as one of the season’s antagonists. I’m wondering if we’ll see a siren too.
In 12x15 Sam mentions wraith, ghoul and siren as the monsters they’ve hunted in a row, and wraiths and ghouls at the time only had had one motw each (plus some mention and brief appearance here and there but not cases), just like sirens, and now we’ve gotten another wraith and another ghoul.
It would make sense to have a siren episode in a season about ‘things that look like other things’, in addition to all what sirens represent.
Now, during the hiatus there have been multiple posts about the features of the demon Asmodeus in traditional demonology (“Asmodeus’ chief objectives are to prevent intercourse between husband and wife, wreck new marriages, and force husbands to commit adultery”) and I’m not sure it is relevant because the show has its own lore that doesn’t really match the source material, but I’ll just put that card on the table too.
