"Richard you're the only one who has the power to stop Thomas Warren. I don't." It's something that makes sense giving what had happened in that clearing. That Warren wanted Richard to come to Geneva and was willing to do whatever he needed to do in order to make that happen.

"And do you think that I'd be able to live with myself if you had the choice between saving the world and saving me and you picked me? Richard, please. Please be sensible. Please."

Alex moves forward, so that she's practically in his lap, straddling him, and not letting him flinch away. "You wanted me to connect you too what's human. That's what I'm doing. Thomas Warren is going to try and use me, use this connection between us to try and get you to do what he wants." Because Alex has the terrible thought that part of what happened in the clearing was to see what it was that Richard would do when Alex was threatened. And they knew: he'd kill.
