[SPOILER] Engineer's last speech

[i3670]

Spoiler below!

I have seen two brothers fall. - Which brothers?

9/11, the fall of the WTC?

Then again, it happened in the 21st century, which is not the "upcoming century".

It'd also be too small of a catastrophe. Some 3000 died in the WTC-attack whilst millions died in the other catastrophes mentioned.

I don't really see how it's related to Mandus' kids either, other than them being brothers.

Also, as all the other quotes are seemingly metaphors, I would think that this one is as well.

The machine tells Mandus that his two sons will die in WW1, in the Somme I believe. Fall in the sense of dying.
