I was sooo torn too, I *hate* hearing spoilers, and I was worried that the sound thing would totally ruin the ep, but it doesn't. At least it didn't for me. As it's not exactly a spoiler since it's the *actual* episode.

As paradise_city said, it's worth downloading and watching if only to get a glimpse of the editing process (although I suppose you could wait and watch it *after* you see the real ep).

I don't know, if we had only had 401, I would totally tell you not to watch them, since they're pretty much a two parter. And after watching them, I really wish, that the rest of the season was *now* but... *shrugs*
