I think the difference is that in a book it seems like a typo if it's not explained, unless you know the character has been exposed to a different accent for an extended period... (And even then it can still seem weird!)People can pick up accents. Ive done it (I sound really wierd with an English accent BTW) but i think it is kind of disconcerting when it happens in a book!

I originally thought it was a typo as well - pronouns can very easily become confusing...ariadne
Because it doesnt seem to specify who the he is...i always assumed it was a typo...but i am just reading it wrong. Like you said Zieria, Ceir says Dell and Angina were too busy...
