Rochelle used to be a news reporter
One thing i noticed about the van she's standing next to is the fact that it looks like the van you see in one of the street levels of Left 4 Dead's No Mercy campaign (It's the one where there's the news van, and the sandbags with the turret behind them)
Also, i wonder why she's holding up three fingers? Oh, and she's also on her cell phone apparently
Also, again, is the big pictures of Rochelle and Coach at the top of the page are pictures of them from the Zombie Survival Guide video (Rochelle = after she saw the Spitter and she started moving away saying "Get back, get back!", Coach = when Nick joked about the Helicopter being made of chocolate)
