“I have no idea!” Lili pushes in front of me. Her mouth is a triangle, her eyes wide and desperate. “What’s wrong with her?”

“She’s having a seizure.” The medic shines a light into Gabby’s eyes, but there’s no color there, only two orbs that look like shiny white marbles. “Has this ever happened before?”

“No!” Lili looks around frantically, as if she doesn’t believe this is real.

The EMT rolls Gabby onto one side and puts his ear next to her mouth to see if she’s breathing, but he just lets her lie there, flailing. She moves like one of those cartoon characters who touch a live wire and light up like Christmas trees, white skeletons showing through skin. I want to look away, but I can’t.

“Can’t you do something for her?” Lili screams, tugging at the EMT’s sleeve. “Anything? What if she’s dying?”

“I need you girls to get back,” the EMT barks. “I need some space to treat her.”

Cars swish by us on the highway. Some slow down and gawk, curious about the ambulance lights and the girl lying in the underpass, but no one stops. Tears stream down Lili’s face. She spins toward me, her eyes on fire. “I can’t believe you did this to her!”

“I didn’t do anything!” I scream through a clenched jaw.

“Yes, you did! This is all your fault!”

The train’s fading whistle drowns out Lili’s words. I refuse to feel guilty for this. It wasn’t like I even wanted the Twitter Twins to come tonight. How was I supposed to know Gabby was going to get so freaked she’d fall into a convulsive fit? All of a sudden, I’m so sick of the Twitter Twins I can barely breathe. “I didn’t want you two along tonight,” I say through my teeth. “I knew you couldn’t handle it.”

The red and blue ambulance lights streak across Lili’s face. “You could have killed all of us!”

“Oh please.” I ball up my fists. “I had it under control the whole time!”

“How were we supposed to know that?” Lili shrieks. “We thought we were going to die! You have no concept of other people’s feelings! You just . . . you just treat us like toys, doing whatever you want, whenever you want!”

“Watch what you say,” I warn her, aware of the medics around us.

“Or what?” Lili asks, turning to Madeline, who stands off to the side with a blank face. “You agree with me, don’t you, Madeline?” Lili says. “Sutton’s a user. Do you really think she gives a shit about our feelings—about anyone’s feelings? Look at how she toyed with your brother! She’s the reason he left!”
