After the ads, everyone gets up off the floor (Rosen's glasses aren't even askew, which makes that the worst riot ever) and finds Wilson's former subordinate-turned-killer crying over the corpse of his boss. Which tells me Wilson was a better boss than I thought, and maybe even a better boss than some of the ones I used to have.
After the sun comes up, Bill is asking Rosen why he was the only one unaffected by the pheromones. Rosen seems to know, but he's too busy with his drug cabinet to explain right now. Gary's worried about the sheet on Wilson getting all bloody, Rachel complains about the persistent smell of the blood, and Nina's talking about the Pushing shoe being on her own foot, although Cameron quickly assures her that it's not the same. Yes, we get it -- they're hot for each other. Rachel rushes home (she probably has a few fences to mend there) and Rosen asks Nina to take Gary back to his house. He's also got a serotonin injection for Cameron, which is how he thinks Bill controlled his flight-or-flight response. Handy how Rosen always seems to have the exact pharmaceutical remedy on hand.
At the bus station, Alice or Tracy or whoever she is is getting ready to board when Matthew shows up. He kisses her and is all excited about buying his own ticket to Chicago to go with her. But she's not down with that. Matthew thinks they can be together, since she's immune to him, but she can't take it any more. She tells him he was the one she was running from, not their podunk little Ohio town. Cameron and Bill arrive, telling everyone to get clear and Matthew to get away from the girl. Of course he refuses, flinging pheromones into the air instead. The crowd starts fighting each other, with Tracy caught in the middle. Matthew really knows how to impress a girl, doesn't he? Cameron and Hicks are trying to fight their way through the battling crowd. And just before the ads, there's a shot of the swarming ants, just in case you missed the point.
