I was wrong. The sirens went off and the whole lab had now the virus. The self destruct sequence went off, and both Hall and I knew what to do. Unfortunately the turn off station is not there. The only one is on the third floor. I told Hall to climb up the service chute to the third floor. When he started to go up smoke came as one of the security installations. Then a bunch of darts started to hit Hall that slowed him down. Right now I am yelling words of encouragement because after thirty seconds the air will be sucked out of my floor. Then he finally did it! He turned it off. All is good. Bit later. We have found out that the virus changed into a non-violent form and now it is safe. <p>
