Clara and The Doctor in “Cold War”

The TARDIS! Where's the TARDIS? You never explained.

Oh, well, don't worry about that.

Stop saying that. Where is it?

Yeah. Well, I wasn't to know, was I?

Know what?

I've been tinkering, breaking her in. I'm allowed.

What did you do?

[mumbling] I reset the HADS.

Huh?

I reset [suddenly quieting his voice] the HADS.

The what?

The HADS! The Hostile Action Displacement System! If the TARDIS comes under attack, gunfire, time winds, the... sea, it... relocates!

Oh, Doctor...

Haven't used it in donkey's years. It seemed like a good idea at the time. Well, never mind, it's bound to turn up somewhere. [The Doctor's sonic screwdriver is heard whirring in his pocket] Ooh. Ha! See? Right on cue. [He examines his screwdriver's readings] Brilliant.

Brilliant.

The TARDIS is at the Pole.

Not far, then.

[sheepish] The South Pole.

Ah.

[to Captain Zhukov, embarrassed] Could we have a lift? [Both Clara and Zhukov laugh as they head back into the submarine; the Doctor laughs sarcastically after them]
