Deacon: Yeah, you can throw blame around all you like, but your boy...
Cole: Athan wasn't the Witness. It's always been Olivia. And right now we need to be ready. She knows where we are and she knows when we are.
Deacon: Jesus Christ. How much time do we have?

We may have saved Athan's soul, but I am losing mine.

Cassie

The last time we gave up was in '57, and then the storms came.

Cole

Jones: I knew that Titan would come one day, but if we could be like Titan...
Cole: We could save everyone.

Whitley: Jones! Jones.
Jones: I need to cool the core, manually, or we'll never splinter out of here.
Whitley: The radiation will kill you.
Jones: Not today.

Don't you assholes leave without me!

Deacon

Cassie: Deacon!
Deacon: Don't leave me.
Cole: We have to go!
Cassie: No, we can't leave him!
Cole: We already have. Come on!

All living things can travel through time. It's simple, really. Just wait a moment, and then another, and another. Do this often enough and you will have arrived at tomorrow. Enough tomorrows and you will be dead, adrift without power or patience. At the very end of time, you will ask yourself, "Where am I right now, and what have I done?" You will have grown old. You will have hoped, and you will have let go of hope. You will have tried, and you will have failed. Shaped by time and you are that you are not meant nor wish to be and you may be left with someone you loved and all the horrible things you've done for them until finally you will lose the very last thing you have left, yourself.

Jones

Guard: What do I care? The world's ending anyway.
Jennifer: I wouldn't sweat it, Chuck E Cheese. I'm Just doin' my part.
Guard: Of what?
Jennifer: Savin' it. [winks]

She was never more protected than she was when she was with you.

Cassie

Jones: I was blinded by my hope for an ending, don't be blinded by yours for revenge.
Cassie: This has only ever been about revenge.

You two want to chase visions. I can't. I'm going to go to 1971, I'm going to find Olivia, and I'm going to kill her, with or without you.

Cassie
