MICHAEL: I know my dad is dead. I understand that. But he went away as well. Why do they go away as well? Dying is bad enough, but going away as well? It doesn’t make sense.

DOCTOR: No.

MICHAEL: That is what confused me. So where is he? Just gone?

DOCTOR: He’s in what I consider to be a very special place.

MICHAEL: Please don’t say heaven. Clouds are just evaporated water. I know this for a fact.

DOCTOR: I was thinking of the past. A lot of people think the past is a sad place, but I visit it a lot, and let me tell you, I find it just as exciting as the present and the future. Your father lives there now, and all the moments where he is a living, breathing loving father are there too. All stored safely. And they will never go away.

MICHAEL: Can I visit him? I’d like to see him again.

DOCTOR: Of course you can, Michael. Anyone who can remember 130 gnomes can certainly visit him. Just close your eyes.
