Plot
Ben is on his own as he no longer knows who to trust, who is dead, and what the secret of Sugilite really is?

And more importantly, back on that thing The Council mentioned behind Ben's back. He learns. Kind of.

We do though. And it's kinda big. Like, series finale big. (Not for a while hopefully but bringing it up so if the series does end suddenly it's on this note.)
