Was it just me or was the ending obscured by one of those one-screen credit thingies.
As for the ep - giving Kenzie powers to make her "one of them" does feel like an easy way of the writers dealing with the whole "she ain't one of us" thing a number of the Fay/Fai(?) have towards her. And while I do think she was v. short-changed by all her friends at a time she really needed them, when she went to see the new-Ash, it wasn't too hard to work out that Ash+Visitior = important meeting going on so stay the fkout of the room. Putting her "butting in" down to "oh that's just Kenzie being Kenzie, ain't she a way" is ... darn it, can't think of the right words, nuts.
btw Kenzie is my fav character but it shouldn't be too much to ask for her to take a mo, before jumping into a situation, to check that something important isn't going on.
