Only person in that room who could turn self-destruct the nukes.Also why be so patriotic as to blow off your own head, I didn't get that, and I know this is being a bit pedantic, but the scene where everything came back online was a little silly. All electricity generation would have failed and only batteries would work (however they would probably be drained too)

That door was weak as bag of poo
Yeah but they were in the room that controlled the nanobots. All they have to do is turn the power off and then maybe the nukes can't ignite their firing sequence!
Killing yourself isn't going to make sure the nukes work, when your in a sealed room, just wait and see, and then be alive too.![]()
That would be so obvious if they did that! Hopefully they will find a more creative way!
The only way I can watch this is if I turn off the part of my brain for logic.
I gave up watching this show at about episode 5, terrible.
