Quote context

[...]

- Whatever the species might be, if you let it alone, it won't bother you.

- Maybe. But if you're wrong, this harpoon will correct any mistakes.

- Mark, we're out for photographs for study, not trophies.

- This thing alive and in its natural habitat, it's valuable to us.

- You don't sound like a scientist. You sound like some big-game hunter out for the kill.

- We may not be back home, David, but you're still working for me.

- You didn't wait long enough before coming up.

- Why'd you shoot? You weren't attacked!

- You sound as though I put the harpoon through you.

- What makes you think we're supposed to play tag with the thing, whatever it is?

- I tell you, we can learn more from it if it's alive!
