When Fernando starts to stir a few minutes later, Cara gives him another shot of truth serum.

"We're pushing our luck," she warns me. "It is entirely possible to overdose on this stuff; much more and we may well kill him."

I stare at her, forcing her to look me in the eyes.

"I know," she acknowledges, sighing, "but we need to get information from him first."

"You're just going to let me die, Cara?" Fernando says softly, now fully conscious.

"You haven't left me much choice, Fernando," she answers, after a very short pause. "Nor much motive, frankly. How did you think I would feel when I found out you killed Linus?"

"I didn't think you would find out."

"Well, I did," she says coldly. "Now, I would appreciate it if you would tell us the names of everyone in Dauntless and Erudite that was working for this Chief of yours. Factionless, too." She already has a sheet of paper in her hands, with a pen poised and ready to go.

I'm ashamed to admit to myself that I expected my mother to be on the list, and even more ashamed at how relieved I am that she's not. I really don't want to have to care so much about her. I am not so lucky with the Dauntless on his list: Harrison is bad enough, but when Fernando names both Shauna and her mother, I hang my head.

"Shauna?" I say sharply. "Are you sure?"

"Well," Fernando says, "Obviously, I'm sure, since you're compelling me to tell you exactly what I know." He shoots me a wry smile. "But I could always be wrong. Good luck with that, Four. I'm sure Zeke won't care at all when you tell him you lost his brother and want to execute his crippled girlfriend."

"Shut up," I say furiously, punching him hard in the face.

"Hitting a helpless man," Fernando says quietly, spitting out blood at me. "Not exactly brave, in the classic sense of the Dauntless credo, is it Four? A little more like Marcus than you thought, maybe?"

I almost hit him again, but Cara actually moves slightly so she's between my hand and Fernando's face.

"Stop trying to provoke him, Nando," she says. "It won't help your situation any."

They just stare at each other for a moment.

"Cara, please," Fernando begs, though I am not sure what he's asking her for.

"I never could have loved you, Nando, even if you hadn't killed everyone I do love. Almost everyone," she amends.

Fernando winces.

"With any luck," he says calmly, "Leo is dead by now, too."

"What's that supposed to mean?" Cara exclaims.

"I signed an order to kill him," Fernando says flatly. "I figured it would help the cause, and it wouldn't hurt my chances with you, either."

"Who did you send the orders to? When?" she demands frantically.

"I just sent them to the team there. I have no idea who read the orders. I left them right before we came here, so he should be dead by now."

Cara emits a strangled scream, which is equal measures fear, grief, and fury. Before I know what's happening, she has grabbed the gun out of my waistband and fired, point blank at Fernando's forehead.

He dies instantly, of course, but unnervingly, he dies with a smile on his face.

"Oh my God," Cara groans, sinking to the floor. "Oh my God. Oh my God. What have I done? What have I done?"

I crouch down beside her and hold her in my arms, and soon she's rocking us both back and forth, repeating her words over and over again.

"It's okay, Cara," I interrupt her. "It's okay."

"No, no, no, no," she says, erupting into hysterical sobbing.

"Cara," I say, raising my voice in alarm, shaking her by the shoulders. "Cara, stop! Stop! Think about Leo, now! We don't know if they got to him. He's been Dauntless for more than 20 years - he won't be easy to take out, no matter what Fernando said. Come on now, we have to figure out how to warn him!"

"Yes," she says, shaking her head. "Yes, yes, yes." She looks up at me, and her raw, tearstained face is heartbreaking. "You will save him for me, won't you Tobias?"

"I will do everything I can," I answer firmly, stroking her cheek. "Okay? But I need you to stay with me, here. I need your help, okay?"

"Okay," she says quietly.

"Cara, listen to me," I start, lifting her to her feet. "Fernando was trying to goad us both into killing him so we couldn't get any more information out of him. Do you understand me? It was a tactic."

A flare of understanding penetrates the misery in her eyes. "He wanted me to kill him."

"Yes."

"He manipulated me."

"Yes."

She closes her eyes and wraps her arms around herself. "How could I be so stupid, Tobias? I'm supposed to be smarter than that."

"You are human, Cara, though sometimes, it's hard to tell. Anyway, we all make mistakes," I sigh. "I was just telling Inez that this morning."

"I know," Cara says distractedly.

"What?"

"I heard you. You were both shouting pretty loud."

She looks then at Fernando, at the rictus of cruel triumph on his face, and the blood oozing from the blackened hole in his forehead.

"I shot a man," Cara whispers, "a man who could only hurt me with his words, and I shot him with the gun barrel resting right on his forehead." She looks up at me, her face as desolate as the ruined landscape outside the fence. "What have I become, Tobias? What is this war turning me into?" She sobs, sinking her face into her hand. "And what will I become," I hear her muffled words, "if he's taken Leo, too, and I have nothing left?"

"You have me," I say firmly, holding her shoulders, "and Tris and everyone else here. All the Divergent, the people your grandfather died to protect. Your people. Don't forget that, Cara," I say, giving her a little shake, and she nods slowly at me.

"I will do my best," she says quietly.

I nod grimly. Now I have two rescue missions to plan: one to Amity and one to Dauntless, and both may well be traps with dead men as the bait. And I can't help feeling as though this is all a design to keep us from exploring beyond the wall. What is it this Chief doesn't want us to find? If this city is really all that's left, why wouldn't he just let us go?

"What is it?" Cara asks.

"I'm just wondering what's really out there."

"Fernando must have been telling the truth, though."

"No, just what he thought was true, what he was told was true. I don't buy it. I think there's still something out there."

Any answer Cara might have made is interrupted, however, by Tris and some Erudite guy I don't know dragging Glory into the room.

"I knew she'd hide inside when you said she was injured," Tris declares, preening a bit. "She couldn't have outrun us, but she could outlast us - I figured you must have told her we were going to leave this place."

"Good job," I nod to her. "Wish we had some way to signal the others to come back."

"I'll go round them up," the man says.

"Okay," I respond, "but don't get too far away. And tell Lou we need her down here."

Glory is pale, the bruise around her eye a florid contrast to her marble skin and delicate features. But this is a different Glory; the cold, gilttering look on her face transforms her beauty into a sharp, cruel instrument. She's staring at Fernando, but her expression gives away nothing - no fear, no regret, no sign that she even knew him.

"Let's get him out of here," I say quietly to Tris, "before the others come back."

"I think we'd better tie Glory up first," she says quietly. "She's not the helpless girl she pretended to be." She mops at the blood tricking out of her nose. "She almost broke my nose trying to get away; Gordon has some nasty scratches on his face."

Even though Fernando was still partially paralyzed, they had taken some precautions, and he has restraints around his legs and his left arm. I unbuckle them and we take Glory to another chair, fastening her hands together and binding her at the legs.

"Doesn't matter what you do to me," she hisses. "They'll get you all."

"Well," I say flatly, "I guess you won't mind answering a few questions, then."

"You're going to kill me anyway," she scoffs, jerking her chin toward Fernando, "so why should I tell you anything?"

"Tris," I say, turning to her, "let's get him out of here now, before we give her the truth serum."

I glance at Glory and am startled to see she's smiling.

"Cara, watch her while we get him out of here, okay?"

She nods, staring at Glory as though she's never seen her before, and in some ways, I suppose she hasn't.

I put my hands under Fernando's arms, and Tris grabs his ankles, and we walk him out to another, smaller room, laying him out on the floor.

"Did you have to shoot him, Tobias?' Tris asks softly.

I take a deep breath and push down the sharp retort on my lips. "Wasn't me," I say instead.

Tris just looks at me, eyebrows drawn together.

"Cara shot him."

Now her eyebrows shoot up, almost all the way into her hairline.

"You were able to beat the truth serum, were't you?" I ask, before she can say any more about it, stepping out into the hallway and closing the door behind us. "Back in Candor, when Niles questioned you?"

"Yes," Tris responds. "Not at first, and it wasn't as easy as beating the fear landscape, but yeah. I could beat the truth serum."

"So Glory might be able to do it, too?

"Yes, I suppose so," Tris says thoughtfully. "She tested pretty strong for Divergence, though she could have faked the test, the way Fernando did."

"No," I shake my head. "I tested her in Candor, with the others. They wouldn't have known about it yet."

"She certainly would have had a lot of opportunities to practice beating truth serum, though, living in Candor," Tris observes. "Maybe Lou will have some ideas."

"Can you get her, bring her here?" I gesture to the next room over. "Then stay there with Cara - she's pretty upset. Fernando told her he put out an order to kill Leo."

"He wanted her to shoot him, then?"

"Perceptive, as always. That was certainly my conclusion."

Tris suddenly reaches up and puts her hands around my neck, pulling me down to her. She kisses me slowly, taking my lower lip and then my upper lip between her own. When she pulls back, she runs a finger gently along my cheek.

"What was that for?" I murmur, voice husky.

"For you," she says, kissing me lightly again. "I'll go get Lou."

Lou is in the doorway soon after. "Cara told me she shot Leo?" she asks.

I nod. Lou just presses her lips together. "Did you make her do that? That is not like her."

"But I suppose that's like me, then? I'm just a killer?"

"I didn't mean it that way."

"Actually, I think you did," I say, pushing my irritation aside. "For what it's worth, I do not enjoy killing, but I do what is necessary." She nods, expressionless. "Speaking of which, we need to be able to interrogate Glory, but she can probably withstand the truth serum."

Lou's brow wrinkles. "Truth serum is not like the others," she comments. "It's just a chemical compound that loosens inhibitions - it doesn't truly manipulate neurological functioning."

"Tris was able to beat it."

Lou smiles. "Tris is an unusually strong-willed person, in addition to being Divergent." She looks at me curiously. "Were you able to beat it?"

I flush at the memory, of all my secrets on display. "No."

"Well, maybe you didn't want to. You're pretty strong-willed yourself, after all."

I think about it and realize that maybe there were some things I had wanted people to know, especially Tris.

"It doesn't matter," I say, shaking my head. "Glory has made it clear she wants us all dead, so she's not going to be inclined to tell us anything and I'm pretty sure she can withstand the drug. Is there anything you can do?"

"Yes," Lou says, after a brief hesitation. I raise my eyebrows at her.

"I can mix the truth serum with some other compounds and one of the cognitive serums. It's still possible she could resist it, but I highly doubt it. Especially if I give her a large dose."

"And?"

Lou hesitates again. "It may kill her."

"Fine," I respond. "Just up the dose slowly so it doesn't kill her too quickly."

"I'm not entirely comfortable with that, as a medical professional."

I shrug. "Then don't kill her. I don't care. She hasn't seen Linus's files, and she doesn't know what we found outside the fence. She won't know where we're going to be. So she can't do any direct damage to us." I stare at Lou. "But don't have any illusions: this woman is pledged to your destruction, and if you let her go, she'll keep working at it." I smile grimly at her. "But if you're more comfortable with murder being my job, you can always just hand the syringe to me."

Lou looks down at her feet. "I'll go mix the serum. Bring her to the medical room."
