Michael pulls up at a park in a white van, where Sam meets him, getting out of the Charger with a rolled-up document that he says is a diagram of the basement at the State Department. Which Sam just had lying around, naturally. He sticks it in the back of the van with the giant crate-bomb already there. Michael sums up their next move against O'Neill: "If we want to get him busted, we need to put him behind the wheel of this van. If he won't do it on his own, we'll have to just gently encourage him." Not to spoil anything, but gentle encouragement is going to be more like a sniper rifle than money-saving coupons.
Back at the safe house, Michael sets down Fi's last packed box from her place, talking in his Irish accent because Sean's lurking around somewhere. They talk a bit about the difficulty of leaving stuff behind, and Fi's impending return home. "I wonder what it'll be loike," she Irishes, looking out the window. Michael Irishes right back that she'll have her friends and family, but she says they don't know her any more. Lucky bastards. She says a lot of who she is is what she's done there in Miami with Michael. He lowers his voice to a whisper so he can drop the accent to show how very sincere he is about all this, but all he gets out is, "Fi, I--" before she stops him. "We're so not good at this," she says. And yet we have to keep watching them try.
When Sean joins them in the main room, Michael tells him to stop parking his car on the side streets. Sean denies having done so, but instead of having alarms go off in his head, Michael argues with him. So they're all completely taken by surprise when a tear gas canister is tossed through the window. Michael reaches for the gun in the back of his waistband, but a beanbag round hits him in the small of the back, fired by a gas-masked commando, and he goes down. More men come crashing in. Sean starts firing, but takes a couple of machine-gun rounds to the body and also crumples. All sorts of weird photography tricks are being used to demonstrate that the gas is rendering Michael helpless and disoriented, even as someone grabs Fi and starts dragging her out. Just as one of the guys is about to shoot Michael in the face, O'Neill stops him, saying Michael has to live. O'Neill removes his mask (just that much of a bad-ass, I guess) and says, "You got some good friends, Westen." He pistol-whips Michael into total unconsciousness and a commercial break.
