I've just remembered 2 important details... Deaton was surrounded by Mountain Ash while he was hanging, and mountain ash only works when the person who puts it knows what they're doing. You can't take an ordinary joe, tell them to sprinkle it and expect it to be effective. So the person who put the ash there must be someone that knows how to use it... and that can be Ms. Morell (but I doubt), Jennifer (we don't know anything about her), mystery girl from epi 1, Chris or Gerard (we don't know what history the elder Argents have with magic).

The next detail is that even though Ms. Morrell told the gang that Lydia can give them the location of Deaton (when he was taken), she didn't actually work with them to help them find him. So I'm guessing that Deucalion is somehow involved with the Darach and his sacrifices (she's an emissary for his pack so hinting to them and possibly stopping the sacrifice would have been bad in Deucalion's books if he found out about it). I mean, we can't take Gerard seriously when he said the Deaton kidnapping may have been a setup, cuz we saw the bugs come for him, right?
