In this scene, we have an astronomy classroom. Christiaan is talking to Dante, who is two seats behind him. In between the two is Shelby. Unfortunately for her, this placement gets her into an awkward situation.

Christiaan: What kind of color-blind are you?

Dante: Red and orange.

Christiaan: And she's [Dante's girlfriend] blue-green? So what would that make your kids?

Dante: I mean, I don't know.

Christiaan: I mean color-blindness is a recessive gene, which means that neither of you can give genes that don't have color-blindness.

Dante: ... Huh?

Christiaan: Okay, blue eyes are recessive, right? So Shelby and I, we only carry the gene for blue eyes. If we were to have kids, they could only have blue eyes.

Dante: *snickers*

Me: 😐

Christiaan: I mean, we're not going to ever have kids- not that I wouldn't want to have kids with you, that's not what I'm saying. I would if we were together! Not that I want to be with you. Wait, that's not what-

Dante: *is screaming he's laughing so hard*

Me: *shifts anxiously in seat, trying not to blush and show how incredibly embarrassed and uncomfortable I am* I get it. Just please stop.
