Finished this yesterday, thoroughly enjoyed it
I spent quite a bit of time thinking about random ways to kill off Miles, and honestly it wouldn't be all that hard if you managed a specific lucky shot. I'm pretty sure that if you, for get, stuck a knife in his neck such that is severed the spine, and left it in there, he'd be stuffed. Sure he could stay alive, but he's still a quadriplegic and you can then go about removing his Goldminds
Also, like a couple of other people have noted I do like the fact that Marasi is a feminine girl who loves her creature-comforts who can still be damned handy and useful, rather than a gung-ho warrior like Vin.
Just my two coppers on the Kandra debate, I've thought from that scene where the Butler tries to kill Wax that the butler was replaced. Wayne notes afterwards that "The tea wasn't even very good", considering the butler's previous comments and expertise involving tea it makes me think that when the Uncle tried to get him to kill Wax, the real butler refused and so was eaten by a Kandra to carry through the plot.
