"I'm looking to see how closely the plants are related to each other," Miguel said, still letting Darcy look at the graph while he explained. "Each line represents a different plant. You can see that two of the lines are quite similar, their peaks and troughs are in roughly the same places. And then the other line is different. So I can tell from this that the plants represented by the green and blue lines are closer than the plant with the red line."
Miguel just gave a smirk at Darcy's assessment of his onesie. "This one is a Spider-Man onesie. So while you're a flag, I'm a super-hero."
