Others' Island (spoilers all books incl RWC)

[Chrischa]

Here's another one; I was talking with my sister tonight (also a big RH fan) and we figured that we also need to look at the actual prophecy that was derived from the objects found by Kennit on the beach. The Other looks at his finds and concludes from them that Kennits deepest wish will come to pass. Kennit interprets that as his desire to become King of the Pirate Isles, but it is more likely that his true deepest wish was to pass on - and thus get rid of - the pain of his childhood abuse. He fulfilled this wish by raping Althea. So how do the drowned kittens, the jewel, and the teacup point towards this wish?
I think the kittens might stand for Althea who was nearly drowned when Kennit pulled her from the sea, possibly combined with cruelty towards a child? What if the connection between Kennit and Thick is that they both suffered as a child? Thicks mother seemed nice but what's with this male figure in the troope who was never to be called "dad"? Did he rape Thicks mother and abuse his son?
The teacup could maybe stand for Bingtown high class that Kennit escaped (actually, his father did, but Kennit never returned of course).
That leaves the fingernails and we've been racking our brains for some connection between the Others prophecy, the outcome that we know and the fingernails, but couldn't find anything. Something about the Paragon or about revenge?
