What you're about to do, Soran, is no different from when the Borg destroyed your world....

Picard: What you're about to do, Soran, is no different from when the Borg destroyed your world. They killed millions too. Including your wife, your children. Dr. Soran: [smiles, sighs] Nice try. You know there was a time that I wouldn't hurt a fly. Then the Borg came, and they showed me that if there is one constant in this whole universe, it's death. Afterwards, I began to realize that it didn't really matter. We're all going to die sometime. It's just a question of how and when. You will too, Captain. Aren't you beginning to feel time gaining on you? [enters control room of missile launcher] Dr. Soran: It's like a predator; it's stalking you. Oh, you can try and outrun it with doctors, medicines, new technologies. But in the end, time is going to hunt you down... and make the kill. Picard: It's our mortality that defines us, Soran. It's part of the truth of our existence. Dr. Soran: What if I told you I found a new truth? Picard: The Nexus? Dr. Soran: Time has no meaning there. The predator has no teeth.
