After the ads, Michael's got a plan -- get a tiny little knife, and make Sam wonder what the hell he's thinking, given that Michael's not in any shape to take on anything tougher than the New York Times crossword. But all he's doing with the knife is cutting some roses from a nearby bush. He and Sam use them to make big bouquets so they can pretend to be delivery guys, hiding their faces behind them so they can get close enough to get the drop on the goons outside. "Why don't we go inside and put these in water?" Michael suggests.
Inside, Michael and Sam explain to Alicia about the bomb in the house. But the only thing that's been brought over is the big new flat screen TV. Michael takes off the back to reveal a big old bomb inside. "Must be one of those 3-D sets," Sam non-sequiturs. Michael says that the radio detonator is cheap crap, which explains why Dennis's equipment has a tendency to pop off early (ahem). Just then, in walks Walt, recognizing Michael and Sam from the previous episode and wanting to shoot them both. And he's deaf to their explanations, because the explosion he survived earlier in the episode made him literally deaf, at least partially. Fortunately Alicia is able to talk him down (or rather yell him down) so he can get curious about whether the bomb can be defused. "Maybe, maybe not," Michael yells. Sam asks, "You guys have any duct tape?" If the answer to that is ever no, they're doomed.
Fi and Jesse are at the university's computer lab asking questions about Mark Sweeney when a skinny nerd gets up and leaves. Jesse gives chase while Fi hangs back to smile at the professor. Michael VOs that most foot chases are pretty short: "Few people have anything left in the tank after a quarter mile at top speed." It's just a matter of keeping the target in sight and waiting to catch up. Which Jesse does. Once Jesse catches him, the kid admits that he couldn't help Sweeney, other than to refer him to a guy at SXG, a defense contractor where he interned. Netted him a hundred bucks, too.
