At first, we learn there's a traitor in Chakotay's cell, and I think "Ah, Seska". But no. Then, Janeway calls from engineering, says Annika has started talking and acting strangely, and I think "Oh boy, Obsidian Agent Seven of Nine again". Wrong-o. Finally, Tuvok tells Neelix that Kes has turned into some kind of energy being and transcended, which I readily accept because we'd seen it on the series. Egg all over my face. You know, fool me once, shame on you, fool me twice, shame on me; so fool me thrice and... I don't know, I hang my head in shame? Or plot revenge. Yes, I prefer that last one.
