Shannon O'Donnell:
I've learned a few details about the Millennium Gate. It's a self-sustaining city, an experimental biosphere. It's never been done before.

Henry Janeway:
What's wrong with the biosphere we're living in now?

Shannon O'Donnell:
Nothing.

Henry Janeway:
Exactly.

Shannon O'Donnell:
But this project will help scientists learn more about our environment, possibly even recreate it on other worlds.

Henry Janeway:
Other worlds! Don't we have enough problems on the one we're on?

Shannon O'Donnell:
Yeah. Which is why I'd like to get the hell off it one day.

Henry Janeway:
I think you're taking this exploring a little too far.
