“We are friends,” I reply, my throat tight with emotion.
 
 “We are friends, Shay. Friends, friends.” She takes a deep breath. “I think I’m going to take a nap.”
 
 “No. Rainey, you need to stay awake. We don’t need to talk, but you have to stay awake.”
 
 “Why? I just need a nap. In case you forgot, it’s been a wild couple of days.”
 
 “We’re running out of oxygen,” I tell her. “If you fall asleep, you may not wake up.”
 
 “Drifting off is better than drowning.”
 
 “They could still find us,” I say quickly. “There’s still time.”
 
 “Is there?” The last word is slurred, and as my own panic begins to set in, I shake my head and pull away, rotating around so I’m on my knees in front of where I was sitting.
 
 “We can’t give up.”
 
 Nothing.
 
 No witty retort.
 
 Just silence.
 
 “Rainey?” I feel for her in the dark and find her lying on her side. She fell over, right onto where I was sitting. “Rainey!” I scream her name and shake her. “Wake the hell up, hunter!”
