[...]

- Don't you talk like that, dear.

(intense tone whistling and buzzing)

- This may be them! Maybe they are coming through from the space platform.

- Humans, listen to me. Due to an error in calculation, there are still a few of you left. You escaped destruction because I did not know you existed.

- Now I know you are watching. I see five of you who have not been destroyed.

- Show yourselves, and I promise you a painless death.

- Just the five of us left? But this is incredible!

- It means that Roy's gone too!

- I'll bet Alice is happy, the way they used to fight.

- Don't say that, Johnny. Roy was a great scientist.

- I would have never developed the serum without him.

- The trouble was he wouldn't admit I was good in my field.
