Ha anyone considered the possibility of a worldhopping kandra? I wonder if that third person is TenSoon, or if he is still alive somewhere, hope so. (I think it is possible, after all I think that there souls were in the spikes, not their bodies, so when they died they didn't move on as Vin and Elend did. All Harmony would have had to do was put the spikes back in a mistwraith and, voilah, TenSoon, the worldhopper.)
Also has anyone considered the similarity between the name Worldhopper and Worldbringer. I'm starting to think that Sazed created, or at least has a hand in running the 17th Shard, which in turn is, in combination with Demoux and Galladon being presumed members of the shard, starting to make me wonder if Hoid is really the good guy we all seem to presume.
(Sorry for the theory ramble.)
