"Don't have that part figured out yet. If we're going to cube him we could potentially - I don't know how much it takes to render morphing impossible like it was for Elfangor, but morphing heals, which means there's lots of evidence we could leave without actually killing him, if nothing else you can get blood out of a person without hurting them too bad or killing them, we could do it in a few stages. I don't know how much of more solid evidence-leaving he'd go for and I'm still contemplating staged causes of death. It might be better to follow him to wherever the Yeerk soaks up its rays and spring him while it's doing that, but that alerts the other Yeerks, so I'd rather think more on the 'fake his death' plan."
