Finally got around to watching the episode, and I loved it, definitely one of the best episodes so far. Them morphing while fighting was awesome, even if we didn't get to see Jin do it too. The other fights were pretty good too. And of course everything with J in it was awesome, too, especially with him talking to the plant, at the end.
Also, am I the only one who thought that the girl who showed up in just this episode got more character development, and was far more interesting than Yoko?
