Fan: Who was your favorite person [to work] with on Doctor Who?
Matt: Each other. Or K-face…I think ultimately, we were sort of spoiled with each other…
Arthur:..like Alex, as well.
Matt: Alex Kingston, very. The most insatiable flirt on the planet.
Arthur: With everyone.
Matt: Yeah, even with herself in the mirror. It’s incredible to witness.
Arthur and Matt: *laughing*
