No, it has nothing to do with the original story (I think) just that the thought of Levi ending Eren's life after all the things has been taken care of (I mean, those titans has been annihilated)
The issues or Eren will be the last titan and Levi will kill him already used in some doujinshi though---but I don't expect that ending---'non-fiction in fiction' /cry again/

The last page is killing me--I'm dying... no.. nooo.. /cries (/TДT)/
