No, no. Just more mysteries. I don't care if it's X or not.
I just want the antagonist to be somewhat more shady until near the end, and for Neuro to use demonic powers to further his investigation, not defend his life/defeat his enemies.
That said, this arc isn't all that bad - it's just going off in a different direction from what I thought Neuro would face, HAL being a supra-genius electronic mind.
