But while Krick draws the blue liquid into a syringe, Bleeding Eyes up and dies. To his credit, Krick at least looks distressed about this. He's not a complete monster!

Back at Harvard, Walter's still struggling to figure out what's making the body float, when suddenly it drops to the ground like a sack of potatoes. He tells Astrid to put the body on a table and notes that it's dropped three feet in the last half-hour. Well, really, it's dropped three feet in the last half-second. Astrid says it's like a dying balloon, which Walter rejects, because balloons don't lose their buoyancy so inconsistently. Something is eluding him, he thinks. Meanwhile, Astrid can't lift Koenig off the ground so Walter goes to help her, only to find that he now weighs a ton. Something occurs to Walter so he tells Astrid to run a test for osmium. She asks him why that would make him float. "It can't, of course. That's what's troubling me," says Walter. Well, thanks for the "explanation."

Elsewhere, Peter and Olivia are using their driving time (presumably after having sex first) to be annoyingly cutesy -- in this instance they're apparently deciding on "full disclosure" of things about the other that annoy them. Olivia's finally figured one out, only instead of saying "don't you know how to use a damn razor?" she says that when Peter's rubbing her back when they watch television he gets distracted and just turns his hand in a circle over and over again, and he disputes her version of that, and they're absolutely nauseatingly adorable. She tells him that it's like he's burrowing through the muscle into the bone, and she doesn't like it, and he smilingly agrees to no more "burrowing" and by this point I'm praying for some sort of vehicular-based monster to wipe out their car and kill the both of them. I mean, it's not like there's going to be any more episodes beyond this season, so I would be happy at this point if these two cutesy-poo lovebirds died happy and we'll spend the rest of the series watching the world fall apart, the end.

Anyway, Olivia burbles about how she loves "full disclosure" and Peter seems a little nervous about it and wants to clarify how it's supposed to work, only he can't come right out and say, "So do we have to tell each other if, for example, we kill a bunch of shape-shifters in an impatient attempt to figure things out for ourselves?" Olivia teasingly asks if he's "holding out" on her, and says it's a great game if two people are playing. Yeah, what's a better game than two people telling each other what they don't like about each other?
