Zee... they've let us die before. Not just in our heads like a training exercise, we actually died. They screw around with us and our bodies every other week. And that's their normal routine. What's to stop them from sending a message if we do something actively to understand them or even to overcome them? I'll be honest with you - it's not turbing in the least. It's scary, and I don't want to see you or anyone get hurt over it... but if you're going to go through with this, I want it to be with me, so that whatever happens, I'm there if and when things go south.

[He hesitates - actually hesitates visibly - and reaches out to take her hand, giving it a squeeze.]

Please.
