^ Just read the issue myself, I believe Olivia is a refernece to Giles' ladyfriend in Buffy Season 4
And giving her surname as "Williams" is no doubt a nod to the Dollhouse
actress of the same name, who played Adelle DeWitt
Also, I'm not sure if we had touched on this before or not, but I had no idea that Giles's Aunts were modelled on Tony Head's own daughters.
I think I had read that, or at least loosely based. Emily Head is fairly famous in the UK for her role in The Inbetweeners
