User blog comment:Coquidragon/Theory about Tatsumi's Death/@comment-4829046-20141122093311

The way I take it, Tatsumi literally can't die. He has yet to complete the "potential" he has with Incursio. I REALLY don't want Wave to die, but I feel that's how it will be. Both he and Kurome will have to die eventually, but hopefully in a different manner from the rest. Unless Wave also has the "potential" to evolve Grand Chariot further, which hasn't been hinted apart from his ownage of Syura.

I would also be fine if they both survive, but still keep to separate ideals. Wave could be pushed to the absolute limit and make him decide to leave the Empire and form his own group that has no ties to either the Empire or the Revolutionaries. But I don't see that happening with Esdeath or Budo around so the likelihood is minimal.

Honestly, it is difficult to speculate anything in this series except when a specific deathflag is raised. ( ._.)
