Outside, Sarah tells Chuck to get as far away as possible, but he's not hearing that, probably because he's already defused a bomb once before. Of course, he doesn't have a laptop or a sexy virus available this time, but a good nerd can always improvise, right?
A SWAT team comes in to back Casey up, and the goons go down, but Yari and Stavros manage to get out. Casey's in hot pursuit, however, and he first subdues Stavros before catching up to Yari and telling him to surrender, which he does. However, just then, an unknown sniper takes out Yari from another direction. We get a look at the guy, who's no one we've seen before, to the best of my knowledge, but is Latino, has a scar on his face, and was on Third Watch. He picks up his phone and identifies himself as "Tommy," and says that the package has been intercepted. "We're going to have to clean things up."
Chuck and Sarah reach the crate and take crowbars to it; they get it open, and we see that the timer we viewed in the opening scene, which now has less than a minute on it, is attached to a large cylindrical container that might well be an explosive device of some sort. As Sarah desperately examines the panel, Chuck wills the Intersect to do its thing, to no avail. Sarah then orders Chuck to get out of there, even drawing her gun on him, but he gets props for staying, and even more for pointing out how dumb it is to threaten his life when she's trying to save it. Heh. They start bitching again, but when it looks like they only have ten seconds to live, Chuck closes his eyes -- and Sarah grabs him and kisses him, long, and slow, and loving...and way more than ten seconds. Heh. They realize this eventually, and are like, "Um..." Sarah tries to spin it as good news/bad news, the bad being that they're uncomfortable, but Chuck says from his end, that's not so much true. Aw. Sarah's unsure what to say about this. She was expecting to die, people! The handbook doesn't cover this!
The next day, Chuck comes to see Lou, who says she knows he's an agent -- but she thinks it's for the FDA. She's not devastated, but more a combination of understanding and interested, as she asks if he ever really liked her. And I have to say that I really like this little moment of the shoe being on the other foot for Chuck -- now he can really understand, a little, what it's like to be Sarah. Chuck earnestly tells Lou that she's everything he's looking for -- he just can't look right now. She nods and thanks him, and then says that the next time her phone breaks, she's going to Large Mart. Chuck: "Oh, that...that hurts." Hee. Chuck says he's really going to miss the Chuck Bartowski (the sandwich), and Lou agrees that she will too, but the kiss they shared was the best she's had in a long time. (I'm assuming this means they didn't have sex, otherwise the unstated implication is a little insulting for poor Chuck.) Chuck does not say the same, but death kisses are always the best, no?
