fringe - "olivia. in the lab. with a revolver." recap

Last night's Fringe was a little meh for my taste. My full recap is up at Vulture, but I'd like to add two things here. First, the guy who played James Heath, Omar Metwally, will soon be seen in James Ivory's The City of Your Final Destination. Second, there seems to be some disagreement over the name of this episode. Most places have it as "Olivia. In the Lab. With the Revolver." But Fox's official Fringe page has it as "Olivia. In the Lab. With a Revolver." More mysteries!
