Also, this is the fourth character in this series whose life has been shaped to suit another's needs, and who has gone through severe mental and physical distress. The others would be Thorn, Blagden and Elva. Too bad he cannot do them much justice.

Now you mention it, Fishy's story is goddamn tragic. I didn't pick up on it because in Paolini's usual fashion it's just treated like a horrible monster and nobody spares it any sympathy at all.

Thorn having a stubbed tail despite him scratching Saphira with it earlier, for example. It is basically an AU, for how much it diverges.

And the retconning is all over the place, as usual. I just hit the big one, which came with the bonus revelation that, yes, the joke about there being Barbie Pink dragons is in fact true. (Well it says "puce", but I looked it up and... yup, that's Barbie Pink).
