Rowan's age wobbles a bit--she says she's seventeen in FL, but in EoT she's too young to drive (although she might have meant that she wasn't licensed, and that looking twenty-ish with the lipstick meant she's less likely to be asked to show a licence). Then Patrick thinks about her 'running the family farm at eighteen', some time in AT or Run Away Home.

I thought I remembered Nick telling Esther or Miranda at some point that Giles had been promoted? To lieutenant would really be the only thing.
