I probably worded it wrong, but basically, they never skipped anything, but a lot of Kyon's thoughts(I can't remember what they were) and Kyon and Koizumi's conversations(again, I can't remember, long time ago) were cut short. In fact, a LOT of stuff was cut short or rushed because they were trying to fit too much into 30 minutes. I mean it probably didn't warrant 2 episodes, but it certainly should've filled more than one. They could've just had the part with Kyon and Asahina in after it. I won't go into it just in case they show it at another point.
But yeah, Endless Eight was meant to be like it was last week, but with a different ending. It does make sense to have this weeks as it was, but I didn't see why they did it, as overall it was a pretty poor episode. I assume next week will be the proper Endless Eight.
