Spoiler:

It should be titled "the Splitting of Kyon" because his ex-girlfriend, Sasaki, is 'other Haruhi' of other-SOS-dan! Of coz there are other "Koizumi", other "Mikuru", and other "Nagato"! Therefore, there is two SOS-dans!

On otherwise, this "SOS-dan of the Dark side(?)" has every member that has similar abilities except that they don't have Kyon.

So, there is other Haruhi, whose name is Sasaki, is always creating Closed Space to make Koizumi very, very tired.

Then it will be a huge problem of Kyon -- would he remain in the "SOS-dan of Light(?) Side" or turn into the "SOS-dan of Dark Side(?)".

Well, Kyon, now we are going to see you are going to be Anakin Skywalker or Luke Skywalker.
