Ah, I think I understand Alpakoka's plot. I thought he meant spreading the triggers to people, but he meant spreading the bomb Evvies to blow up next to everyone as a sort of assassination plot.

I imagine some incompetent guy putting a bomb in her tail, gloating that he can kill her at any time. However, she detaches her tail and throws it at him and he looks down at it in annoyance at his own stupidity before blowing up.
