He's rambling, but Liz is just — enchanted. Not in the boyfriend stealing kind of way, but where has this fellow science-inclined mind been all her life? She was always that lone person in science labs and classes who was a little more into the subject material than the rest of the class, who had a tendency to reference experiments and biologists who even the teachers were sometimes unfamiliar with. To hear someone talk as passionately about something she just loves is — it's nice.
