Lost, Season 5

Tony:
Over here. We were cutting through the rock, right on your specs. That's when the drill melted.

Pierre Chang:
The drill melted?

Tony:
Yeah, yeah. 3 meters in. We went through six carbon drill bits, and the last one just fried. Then my operator starts grabbing his head and freaking out. We sonar-imaged the wall. There's an open chamber about 20 meters in, behind the rock. There's something in there. And the only way to get to it is to lay charges here and here and blast through it and take a look--

Pierre Chang:
Under no circumstances! This station is being built here because of its proximity to what we believe to be an almost limitless energy. And that energy, once we can harness it correctly, it's going to allow us to manipulate time.

Tony:
[Chuckles] Right. Okay, so, what? We're gonna go back and kill Hitler?

Pierre Chang:
Don't be absurd. There are rules, rules that can't be broken.

Tony:
So what do you want me to do?

Pierre Chang:
You're gonna do nothing. If you drill even 1 centimeter further, you risk releasing that energy. If that were to happen...God help us all.
