I can't fall asleep. I lay awake thinking about the simulations, and the fear landscapes, and what will end up in mine.

I notice Sasha leaving the dorm. After a minute of contemplating, I get up and follow her.

Sasha walks toward the pit. I silently walk behind her. When she reaches the chasm, she stops and stares down at the water.

"Sasha," I whisper.

Sasha turns.

Realization hits me.

"Sasha, you're not-"

"You don't understand, Ha. There's so much you don't know."

"Is it really something you should kill yourself for? Why don't you talk about it. Is it your parents?"

Sasha shakes her head. She sets her hands on my shoulders and leans in close. I can see she's crying.

"Ha, listen. I..." she pauses and glances around. "I'm Divergent."

Divergent.

I remember Trista saying that word. But what does it mean?

"What's Divergent?" I ask.

"It's something very rare. It's where you get more than one faction as your aptitude."

"But that's impossible!" I interrupt.

"No, it's not. It's just rare. I had two results. Dauntless and Abnegation."

I suddenly realize that Sasha is more selfless than brave. I should have noticed.

"I had no life in Abnegation. That's why I came to Dauntless with you. But my Divergence makes me aware in simulations. And Kaden discovered me. That's why so many Dauntless members were watching me. They know, Ha. They know I'm Divergent."

"Is there a problem with that?" I ask. I'm panicking. How can I stop her from jumping in the chasm?

"Yes. Everyone thinks Divergents are a threat to the faction system."

I just stare.

"They're going to kill me. The first chance they get."

"Then escape."

"I can't. They'll find me."

I let it all sink in.

"I can end it all now." Sasha whispers. "Then I won't have to face it."

"You can't!" I gasp. "What about me?"

Sasha sighs. "It's better you lose me now than lose me when they find me."

"This isn't being selfless. And it's not brave to not accept your fate."

"Maybe it's not the selfless or the brave part of me. It's the Divergent part."

My mind goes blank.

"I'm sorry, Ha. You've been my best friend. You don't deserve this. But it's meant to be."

It's now that I realize I can't stop her.

"I'll miss you."

Sasha pulls me into a hug. "You can make it into Dauntless." she whispers. "I know you can."

She walk over to the edge of the bridge. I stare helplessly.

"Be brave." I whisper.

She stares at the water for a moment. Then she grabs the railing and hoists herself over it.

I stare at the spot where she stood only a moment ago. Then my legs buckle and I drop to my knees.

Why?
