"There are always possiblities"...

Spoiler for Oh Boy...:

There is one other point that could correct the loop. When Kyon goes back in time, what happens to those on the room he was in? He disappears. Does "human" Yuki, or Haruhi still have powers that they don't know of in this universe? Did past Yuki in setting up the escape system also set a preprogrammed delete on events post-Kyon? Does that universe end when Kyon leaves, or when Kyon comes back to stop Yuki? Or are there more than one alternate timeline involved here?

Then there is one other point...when Kyon is stabbed...there are three Kyon's in that universe. The one from the "normal" time, the one the as been "leaping", and the one from the "future". Thus it is possible that the one not involved with the battle is the one that got away in a version of the world where Kyon died, because those events would effect how that version's life would go. Thus there may be two versions of "Kyon telling Yuki and Mikuru to go back into the past". One is the non-time traveling Kyon that was not stabbed, the other is the one that was stabbed remembering when the "other" Kyon saved him. Thus a time loop that overwites itself.
