Nurse Lois is tending to present-day Oliver. She's put a washcloth to his forehead. "Look at us, the noble couple," she says. She tells Oliver that she let him go so he could go save the world. She doesn't think this is saving the world. She thinks he backed out of their deal. Oliver can't hear her. Lois wonders if they didn't have it wrong and that neither of them is a hero. Lois, about to cry, says she wonders if she should have let Oliver go. Clark shows up. He asks how Oliver's doing. Lois just shakes her head without turning around. Clark puts a hand on her shoulder. Chloe shows up behind Clark. This is the scene where everybody sneaks up on everybody else. Chloe asks if she can talk to Clark. She shows Clark a bunch of papers and files lying on a table. They start talking about finding an antidote. Clark asks how they can find an antidote to a poison that's not in any public database. Chloe says they'll have to name it themselves. You can call it, "Lameacillin." Chloe rattles off stuff about cyanobacterias, chloroplasts and robodimensional paradoxes (sorry, my mind wandered) and presents Clark with a solution: she's found a flower that matches. This is when Chloe goes into hyperverbal mode, going through papers on the table and completely confusing Clark.
