So Clara takes off with a Tardis that is stuck looking like a diner. Fussy chameleon circuit it seems. Sort of the same as the Doctors Tardis.
Clara can drive a Tardis, also she reads Gallifreyan. Clara can close the Tardis doors with a snap of her fingers.
Kind of beginning to think, there’s only the one Tardis. In The Name of the Doctor, Clara points the first Doctor to the Tardis. I’m thinking that, that is the original Clara, after taking “The long way round”.
Also thinking that the Tardis, resisted Clara in the early days, because the Tardis knew what was ahead for Clara, and breaking every rule, was trying to re-write the future.
