Emily: Huh. Well if you were alive you would be used to it, and you probably wouldn't even think about it. Like how time travel makes so much more sense to you than it does to me.
Dee: There's not that much to get! Oh, and that's another thing - I'd lose all that. I'd be stuck in two dimensions.
Emily: Don't - don't you mean three?
Dee: No, two dimensions.
Emily: But time's only the fourth dimension, so don't you still have the third? Depth, or whatever?
Dee: I'd say I'd be losing height as well as time.
Emily: You wouldn't lose height, what are you talking about?
Dee: Basically I would! We all exist in four dimensions, but you can only really move in two, since you're confined to the surface of the Earth. And at this scale, it's almost flat. Sure, you can jump, or climb a tree, but that's not much. You could get in a plane or a submarine but that's expensive and you can't just do it on your own. Even then, you're still limited to certain regions of the atmosphere, ground and sea. I can fly to the other side of the universe! I can go there faster than the speed of light!
Emily (sticking her tongue out): Oh, live it up. I wish you could take me.
Dee: Yeah, I really wish that too. ... But I think... the main reason I wouldn't really want to be anything else is... this is my identity. Death isn't just a job, it's who I am, you know?
Emily: It's what you are, not who you are.
Dee: No, it's both.
