When Gillian is with David do you think she has american or british accent?

American accent, definitely. She says when she’s in the US, she uses her American accent automatically, and when she’s in the U.K. and an American call her for example, she switches into her American accent. So I think she adapts to the person she is with.
But it’ll keep me guessing forever, though. I mean, I really wonder what accent she uses when she’s angry and yell, or with which accent she thinks or dreams. I wish I was in her head for a day, just to see how it works!
