Zest went out like a true Player, especially considering he really had no reason to go out like that other than to give himself a really cool death scene. I don't think he had any more beef with Signum or anyone else at that point.

And Nanoha....God Damn. A 5 cartridge rape party on #4 (Who should have been disintegrated you would think) and then she whips out that craziness on Vivio. That was the most brutal looking piece of magical pwnage I've ever seen. I get the impression that Nanoha she can't actually go use her maximum strength unless she likes her intended target.

And what happened to Vita? Is she dead? You wouldn't think Hayate would just leave her there in the ruined engine room.
