Awesome Episode, really enjoyed it... @jacob_paige by getting them to kill eachother means there is more chance of getting both in case they were otherwise separated when the attack came.

So was China also developing the machine (possibly with Snow's help)? Or were they referring to some other machine?

Was wondering how he survived and she didn't when he was the one with a bullet in him.

Why bother ordering them to kill each other? The missiles would have done that for them and with much greater certainty since they would have stood there and waited for them.
