[Archer is silent through Zulf's explanation. Needless to say, he's somewhere between horrified and morbidly fascinated. How could something cause destruction that wide-spread? How did they survive? Why did this happen? Why does Zulf thing he could have prevented it? It sounds more like a natural disaster. He waits a moment after Zulf finishes speaking to take all that in, frowning slightly.]

Why do you think you could have prevented it? It sounds like you had no idea it was going to happen.

[There's another pause while Archer tries to find words to express his sympathy for Zulf. He's never been any good at this.]

I'm very sorry to hear about all this, Zulf. I never would have imagined you've lived through something this horrible.

[All your friends and family, your fiancee... It's hard to imagine.]
