A bright light is behind them. ) Clara: I told you it'd work! The Doctor: It very nearly ate you for dinner. Clara: Oh, admit it. I totally saved your life. The Doctor: It wasn't going to eat me. Clara: ( laughs ) I totally saved you from having to marry that giant sentient plant thing. That bit where I jumped over the side? That was amazing! Hah! I knew you were impressed!

I gave you this number for emergencies. Rigsy: It's an emergency, trust me. Just... Rigsy (O.C.): Come and take a look at it. Please. The Doctor: Who said you could give out my number? Clara: Look, look, no matter how bad it is, we cannot take you back down your timeline just to fix a tattoo. Rigsy: That's just it. I didn't get a tattoo. And it's... It's counting down. Clara: Sorry, what? ( Rigsy holds up a mirror and we see the number 538 on the back of his neck. ) Rigsy: The tattoo - it's a number and it's counting down to zero. Clara: Hang tight.

  SUMMARY:
output: The Doctor and Clara receive a phone call from Rigsy, who informs them of strange numbers that have appeared on the back of his neck that are counting down with no memory of how he got it. After examining him, they trace his movements to a trap street in present-day London that houses extraterrestrial refugees. They then discover Rigsy was sentenced to death by Me, [N 2] the street's mayor, for murdering an alien called Anah and that Rigsy will be killed by an alien raven when the tattoo, known as a Chronolock, reaches zero. Clara discovers that the Chronolock can be transferred to a willing recipient and takes it from Rigsy, believing that Me will spare her, buying them more time. The Doctor realises from the medical data in the stasis pod Anah is stored inside that Anah is still alive; Me made a deal with an unknown party to have the Doctor transported far away to keep the street safe. As the Chronolock has been passed on to Clara, Me cannot remove it and Clara cannot be saved. Clara pleads with the Doctor not to take revenge for her. The raven kills Clara, and the Doctor is teleported away.
