I believe one of the consequences of Lasciel being the whispering shadow is that her coin must not be locked away behind a warding circle.  It's at least strongly suggested that one of the effects of Lasciel's coin being buried in the concrete floor of Harry's lab was that Lash could diverge in personality and motivation from Lasciel.  If Lasciel had been able to check up on the process while still being locked in two circles and buried, I don't think Harry could have had as strong an influence over time on Lash as he clearly did.

Ok, so I don't mean to be the blonde dummy here but did we ever find out exactly who the woman was at the end of Changes? Are we assuming it was Mab? I can't seem to be able to find a specific answer (and my talent with the search box ends when I clear the word "Search...") and I didn't want to write a whole new topic if everyone has discussed it somewhere else.

Yeah, that bit really bugged me too! In Death Masks as well, Mort was described as "...A dumpy, balding man in his late forties..." which also does not translate to "self-destructively obese." Could it be that Harry was just trying to be nice in his descriptions of him before, and that now that he's dead he doesn't care as much about the potential for offending someone with an honest description? Or maybe now that he's dead he's seeing and remembering things with less self delusion. (Of course that doesn't in any way cover the house changes, but whaddaya do?)

Here's another thing: Every person that Harry has encountered since he died seems to have become a sort of idealized version of themselves. Take a look at the descriptions of Carmichael and Captain Jack, as well as Mort. (Obviously, since we've never met Sir Stuart before we have nothing to compare him with.) It made sense to me when we were just dealing with the dead guys; you've got that whole frozen at 30 thing going on and all. But it seems like he's seeing Mort (and Mort's yard, and Mort's house and its furnishings) in idealized forms as well.

If it isn't just one huge continuity flub (and it seems as if it's much too big to be one) then I'm guessing it's a 'dead' thing.

Has anyone brought up the fact that Ortega can't be from the 13th/14th century because in changes Lea says that Arriana turned Ortega because he was a conquistador which would put him at the 16th century because the conquistadors didn't go to the Americas till then so Arriana would have no reason to hate conquistadors until then.

Does it say so in SJ?  I don't have my copy with me.
