NOTABLE QUOTES

Astrid:

"What you're feeling right now, it's just the effects of the LSD. But it's temporary."

Broyles:

"No. It's infinite. It's all around us. You don't see that? I didn't see that. But now I know. And I know it followed me."

Astrid:

"What followed you?"

Broyles:

"Death. I saw death. All of it. And it was me. Can you hold my hand? Please."

William Bell:

"Walter, when we were young and foolish with too much power and too many dreams that no one could stand in the way of... we needed each other."

Walter:

"I don't understand."

William Bell:

"We needed each other then, to check and balance."

Walter:

"And now?"

William Bell:

"Now you possess the wisdom of humility. We didn't back then. The decisions you make will be the right ones. The direction you choose to take will be just."

William Bell (to Olivia):

"You should have been safe inside your mind... except it's you, and you have never felt safe. You are your own worst enemy, Olivia. You took the opportunity to let your fears overwhelm you, but you just fought back. In the end, you are as strong as Walter and I always believed you were. And now you know it too."

Peter:

"Who is this guy? I saw him in your mind. You had him locked up in a zeppelin, he was just flyin' around trapped in there."

Olivia:

"Yeah, I don't know, I haven't seen him before. But I think that he's the man who's gonna kill me."
