McFadden tells her to follow him, and he takes her over to a computer screen where a tech runs an outbreak simulation, showing what happens if just one person gets out and infects someone on the outside. The map quickly goes from street level to a view of North America that shows the continent being overrun in just two weeks. Naturally, I look at the map for places I've lived. Amusingly, you can see a big outbreak between Fort McMurray, where I lived for six years, and Fort Chipewyan, which is more than 200 kilometres to the north. I say "amusingly," because the outbreak is growing in an area of northern Alberta where nobody lives. And by "nobody" I don't mean a bunch of small towns, I mean "nobody." Well, apart from the scattered hunter and trapper, I suppose. But to get from Fort McMurray to Fort Chip, you have to either fly or wait until the winter to drive, because a portion of the ground trip happens over an ice road that's built in the winter and unusable by the spring. So I love that one of the epicentres for the spread in Canada is in this no man's land. Other viewers might have seen similar incongruities in parts of the map based on their geographical knowledge.

ANYWAY, the point is that there are a bunch of angry circles depicting sick people -- and then we go to the world view as the world slowly turns red. On the plus side, it looks like the sea people of the Atlantic Ocean will be immune. "We have no symptom blocker, no cure. What solution do you propose, Agent Dunham?" Olivia just stares at the screen.

In the office building, Walter removes, to Astrid's horror, his vacuum-sealed helmet. He grumpily tells her that it doesn't matter, because the virus isn't airborne, and is transmitted through bodily fluids. Yeah, and twelve people in that office have managed to contract it, so I think all things considered, I'd rather have the helmet, but of course Walter's also reckless because his son has been exposed, and Astrid recognizes that and tells him that they're going to figure out a solution and Peter's going to be fine. Walter doesn't say anything.
