In the I'm-not-sure-what-letter-this-plot-rates: Lloyd visits Olivia at the hospital and apologetically explains that he wouldn't be bothering her, except there's the slim chance that she might remember some of the formula that he -- and presumably she -- saw in their flashforwards. Olivia misses the chance to say, "Dammit, Lloyd, I'm a doctor, not a physicist" and instead rattles off her memory: She recalls getting up from the bed after Lloyd excused himself to make a phone call, and staring at the equation. None of it made sense except the chemical formula for halothane, which is an anaesthesia. She scribbles it out for him (C2HBrClF3) and Lloyd muses, "Quantum mechanics and anaesthesics... that's what Mark and I were working on in our flashforward. I thought 'QED' meant quantum electrodynamics, but we were building a quantum entanglement device." Olivia gives him the Dammit, Lloyd, I'm a doctor, not a physicist look, then takes off for rounds.
In the B-plot: Keiko's taken Emil to her sushi joint of destiny and filled him in on why she goes there. Emil, who truly is a thoughtful cat, says, "I can respect that. You saw your fate and now you're doing your thing." Keiko tells him, "When I saw my future, it was the best day of my life. It was the first time I let myself want what was in my heart. So like you say, I am doing my thing." Emil is smitten. Keiko asks what he saw, but he says only, "Something different than you. Let's leave it at that." Keiko tells him he's kind to have given her a job, and he replies softly that they're lucky to have her. I pause the DVR so I can take out a notebook and write "KEIKO + EMIL = TLA" and "TEAM KEMIL" all over it, then resume right in time to see my other star-crossed pair, Bryce and Nicole (BRICOLE? NYCE?) heading toward the sushi joint. Oh noes! Destiny will not be denied! Except it will because at the last minute, Bryce decides he's not in the mood for sea urchin. What he wants is to kiss Nicole. Which is awesome and I am cheering because Bryce so obviously digs her and vice-versa, but Nicole is really freaked out. Because of this little drama, they miss seeing Keiko pouring Emil another cup of sake.
The next day: Emil's morning -- which is already off to a bad start because of his hangover -- gets worse when the INS comes in and arrests him for employing undocumented workers. The agents bust the place and Keiko is cuffed and loaded into the van with the other presumably-not-here-with-full-permits workforce. Naturally, her detaining van goes rumbling by right as Bryce is sitting at an intersection and leaving Nicole a really sweet message. O, star-crossed lovers! Whom I am rooting against anyways!
