A preppy student who often picks on Uzi. Unlike Thad, who only looks and sounds like a stereotypical meathead jock, Lizzy plays the archetype of the high school mean girl to a T. She's obsessed with fashion, heads the cheerleader squad, and always has her nose deep in her phone. 

A supporting character. Caitlin Dizon is a good frame of reference in the original series. Her voice is haughty, sassy, sounds disinterested in the world unless she's the center of it, and enjoys picking on Uzi.

CONTEXT:

• Line 1: Lizzy is giving her class history presentation on Khan's doors. Not only is she completely disinterested, reading off her phone while giving the presentation, but she hasn't done much, if any, research. It's an understatement to say she put almost no effort into this.
• Line 2: After Uzi's presentation ends with her blowing up the classroom and being sent to the clinic, Lizzy drops by to kick her while she's down by likening her to an ugly growth. It's petty high school bullying stuff. 
• Line 3: Lizzy has just found out that Uzi has left the colony, and is now taking a victory lap. She's believed Uzi was going to get herself killed if she persisted in her desire to leave, and now that she has, Lizzy feels vindicated. She's explaining this to Thad, who was always more lenient on Uzi, and feels like she's won an argument.
