Scott finally learned the truth about himself in "Currents," we lost another member of the team and Derek discovered how Erica went out fighting. All in all, it was a very satisfying episode of Teen Wolf.
I thought after last week the sacrifices were over, but it really didn't matter, as it doesn't seem there are any dark druids in play at all. It has all been a ploy to get to Scott. We essentially knew Deucalion wanted Scott all along, so why all the dramatics? If he had done any homework on his prey at all, he would have known that the further he pushed Scott the more likely he would be to find out about himself.
