[The Doctor continues to stare at Vira. The age in those brown eyes are showing. Because he's thinking about how his 4th face died to save the universe. How his 5th face died to save Peri. How his 9th face died to save Rose. Yeah, someone is a bit of a magnet for trouble. He's just lucky on-top of the fact. This face was lucky that when someone got their hand cut off. He could still grow a new hand. Was still in the time-frame of the regeneration cycle.

The Doctor isn't sure if Jack knows. That The Doctor would be the one who runs, back into a burning building to save everyone. Making sure everyone is out. The Doctor making it out is optional.

It is inevitable. Someone will die again here. The Doctor can't walk away; even if he will know in his hearts, that dying will hurt Jack. And his other friends.]

Not careful. Clever.

[Ten corrects Vira.]
