The first time Methos saw a blue London police box, it was 1935.

He was surprised when the door opened with only a little coaxing, and even more surprised when the inside revealed a perfectly ordinary desk and stool.

How natural it looked now, slotting into place on a twentieth century London street. How alien it had seemed the first time, half-buried in sand in the Kingdom of Ma'in. Eventually he realised for the Doctor, it had been their third meeting.

"Twentieth century London? Wouldn't be my first choice."

Maybe he'd stick around a little longer though. Just in case.
