It's been, what, two weeks since I've last updated? Sorry, but I hope I made up for it with this chapter. I left the ending a cliffhanger (I know, I'm so cruel).

I don't need to say I don't own Attack on Titan, do I?

Reviews are nice, but they are not required. You can review if you want.

On to the story!

(Levi's POV)

I rub my bump as Clyde surveys the area. We're sitting in my room with the curtains open. Clyde stares at me when I hum to my baby. His ears perk up whenever he hears a noise. I sigh. It feels like I'm being babysat.

"So…" Clyde begins. "That baby isn't Erwin's is it?"

I turn to him and raise an eyebrow. I knew he would figure it out sooner or later. He's been here for two weeks. I shift a little at his question.

"What makes you think that?" I ask, my red eyes boring into his yellow.

He sighs and runs a hand through his blonde hair. "Do you really need a reason? Every time you're away from Eren, you get weaker. Every time you drink his blood you feel better. I smell his scent on you. He marked you, didn't he?" Silence answers him. "So, how far along are you?"

"Eight months."

"You're ready to pop aren't you?" Clyde sighs. "When did he knock you up?"

"It was during mating season, his first mating season. We haven't experienced any mating side effects because we're already mates. Annie's been experiencing them."

"Annie?"

"The other vampire that lives here. Eren's…uh…girlfriend."

"You're his mate. He cannot be with anybody else." Clyde says. "That must be why you're feeling weak. The bond is breaking."

I shake my head. "I know, but how can I tell him that this is his child? He wouldn't believe me."

Clyde looks up and his ears perk up. "I think he would believe you. Just tell him. You love him right?"

"More than anything." I say.

"Then tell him. Tell him he's a father. He'll believe you. I've known him for a while. I may not have been around for his whole life, but I know him. He'll be happy." Clyde pulls me into a hug.

"Thank you for the advice Clyde. I'm glad I'm carrying Eren's child. Now let me give you some advice." I say as I pull away. "You should ask Erwin out."

"W-What?" Clyde asks, his cheeks turning pink. "W-Why should I?"

I tap his nose. "Don't act innocent. I've seen the way you look at him. Ask him out."

"You think he'll say yes?"

"I'm positive. If not, I'll kick his ass."

"You sure are violent."

"Hell yeah." I say as I plop down on the covers. "You'll get used to it."

(Eren POV)

How the hell is that possible? I walk away from Levi's door. I replay Levi's words over and over again in my head. I'm the father of his child? Erwin's not the father? I am? We never had sex, did we? I think back to eight months ago, when I went to the kitchen to get a blood bag. My erection was straining against my pants. I remember looking back and seeing Levi, flushed and confused. I see flashes of Levi panting, his eyes clouded in lust as I entered him. I remember the taste of his blood when my fangs dug into his neck. I remember releasing inside him and….shit. That was it. I brace my hand against my head. I had sex with Levi and I never knew it. I impregnated him. He probably hates me, but he said he loved me.

"Eren, what's up?" Hanji asks when I make my way into the kitchen.

I dig my nails into the counter, the marble cracking. "How long has he been suffering while I was gone?"

"Excuse me?" Hanji asks.

I grab her collar. Annie comes over and pushes me away from Hanji. "You knew all along didn't you?"

"Knew about what?" Annie asks.

"About him being a father." Hanji says quietly.

Annie looks confused. She looks between the two of us before I see her eyes turn red. "You impregnated her?" She asks loudly.

"He didn't impregnate me."

"For Hell's sake Annie, Hanji's a lesbian." I say. By this time, Levi, Erwin, and Clyde have appeared on the staircase. I brush Annie away from me and approach the staircase. Erwin and Clyde step aside to allow me to stand in front of Levi. His eyes are wide, almost all of the red drained from them. I brush his hair back behind his ear before I quickly descend to his neck.

"E-Eren?" He asks. In answer, I sink my fangs into his neck. An electric spark shoots through my body as the first drop of his blood hits my tongue. His hands fist into my hair and a long moan escapes his lips as I press my fangs deeper. I rip my fangs out and dart my tongue across my bite marks. They heal almost immediately. I catch Levi as his body sags against mine.

"What the fuck just happened?" Annie asks.

Hanji and Clyde step forward. "You must be Annie." Clyde says. "It's nice to meet you. I'm Eren's friend. I'll let Mrs. Hanji explain it to you."

Hanji chuckles. "Well it's quite simple. Eren was re-marking his territory and the bond is not broken."

"What do you mean, re-marking his territory?" Annie asks.

"Well, you see…"

"I'm not the baby's father." Erwin says. "Eren is."

"I don't believe that." Annie says. She starts to walk up the stairs. I stand in front of Levi. "Eren is Levi's mate?" She reaches out to touch my cheek, but Levi growls and hisses at her. She hisses back and moves away from us. "So it is true? When did it happen?"

"During Eren's first mating season."

Annie's features contort in rage. "You planned this didn't you? You wanted Eren to knock you up you whore!" She rushes out the house, leaving the four of us to sit in silence.

I turn back to Levi. I brush my fingers through his dark locks and kiss his forehead. "So, what now?" Levi asks me.

"We wait for her to be born." I say as I brush my fingers against Levi's bump. "Have you thought of a name yet?"

"Hmm, no, I haven't." He says through heavy-lidded eyes. "Lemme sleep first."

I sigh and pick him up bridal style. I go up to his room and tuck him into bed.

"It's weird, finding out you're a father in a day." I tell Clyde.

"I knew the minute I walked into the house. He was covered in your scent. That baby's strong, like her father."

"It's funny. Before, I'd feel weird about kissing and loving another guy, but now..."

"Now you don't care. You just want to be with him." Clyde finishes for me.

"Yeah. You think I would make a great father?"

Clyde nods and places his hand on my shoulder. "I know you'll be a great father. Your parents and your grandfather would be happy."

"That I've knocked up my mentor?"

"No, that you've found a mate." Clyde moves to the door. "I'll go scout out the slayers, see what they do next. Have fun with your baby momma."

I stick out my tongue like a little child. Clyde laughs before closing the door behind him. I look back to Levi. His even breathing tells me that he's asleep. I lean forward and kiss his cheek. "I'll be back later." I say before I join Clyde downstairs.

"I thought you were looking after your mate."

"He'll be fine. I'll only be gone for a few minutes."

"Don't take too long." Hanji says. "It'll cause him great pain if you are gone for too long."

I nod and grab my grandfather's necklace. I clasp it around my neck and grab my scythe. "Take care of him for me?" I ask Hanji.

"What do you think I've been doing?" She asks with a playful smile. "I'll take care of him."

"I'll take care of him too. Hanji, you should call Isabel here too. She hasn't seen her brother in eight months." Erwin says.

My eyes widen. "Isabel is Levi's sister?"

"Adopted sister." Hanji says. "She was an orphan, but Levi took her in. They were the best mentors at the slayer academy. Then, one night, as they were walking home, Isabel disappeared. Levi looked all over for her, but he couldn't find her. I found her and fell in love with her. As for Levi, I think he got into a gun fight with another slayer and he was shot. Erwin smelled the blood and found Levi. He turned him, and that leads us to this point in time."

I nod my head and turn to Clyde. "Ready?"

"Yeah. Let's go."

"We'll be back." I say as I walk out the door. Hanji waves to us and tells us to be safe. Clyde leads the way to Grisha's house. We hide in the bushes. I peek up from the bushes to see Grisha waving a needle in front of my sister Mikasa. He injects the needle into her neck and pushes the black liquid I saw a month ago into her flesh. A scream bubbles from her throat and she falls to her knees. I watch in horror as her skin turns pale and her eyes turn to a pale blue. White wings sprout from her back and two tiny horns grow from her head. She screeches and stands from the ground. Grisha smiles and walks around her in a circle.

"Sir, the preparations have been made." One soldier says beside Grisha.

Grisha nods and looks into Mikasa's pale blue eyes. "You know what you have to do." He hands her a sword. "Eliminate all of the vampires."

She nods, her eyes turning to an icy hue. "Yes…Master." Her head turns to the bush we're hiding in.

"Oh shit." I say as she charges forward and grabs my throat. She hoists me up and throws me to Grisha's feet.

"Well, look what the cat dragged in." Grisha says. "You're just in time to test out my new experiment." He says as he produces another needle loaded with black liquid. "You can't resist this one now. I changed the formula. You will become a mind slave for my kind. Nobody can stop us Eren. Nobody." He plunges the needle into my neck and pushes the liquid into my bloodstream. My hands weakly come up to cup my throat as I fall to the ground. My screams echo around the crowd of slayers and hunters gathered around me. I curl up into a fetal position and whimper as the pain laces into my veins. I hear the slayers and hunters cackle at my broken state. I hear a growl and shrieks. The faded sounds of flesh being ripped and shredded soothe me. I scream as something sprouts from my back and my eyes burn. My fingers dig into my throat and I feel my fangs elongate. A growl bubbles from my throat and I quickly stand as the pain fades away. Voices echo in my head. Kill, Kill, Kill all vampires.

Grisha gasps as he looks up at me. "It worked. My experiment worked."

A distant growl has me turning my head. Clyde dashes forward and slices open the chest of one of the slayers. "What did you do to Eren, you cunt?!"

Grisha approaches me and smiles. "I'm using him to win this war." He grabs my chin. "Kill him."

My limbs move without my permission. I grab my scythe and run towards Clyde. He manages to dodge my first attack, but when I slice his shoulder, he hisses and moves back. He licks his shoulder and the wound closes. I stand still and fight to gain control of my body.

"C-Clyde….get…a-away…from…here."

"Eren?" Clyde asks as he lowers his weapon.

I grit my teeth together. "G-Go..protect…L-Levi." Pain wraps around my body as I close my eyes and bite my lip. "GO!" I shout out before I lose my fight and rush forward and slice Clyde's chest. He hops over me and runs in the direction of the house. I go to chase after him, but Grisha holds out a hand to stop me. "He's of no use to us anyway. Come. We will go to the front lines. Eren, Mikasa." I lower my scythe and follow Grisha, Mikasa trailing behind me. I still fight to gain control of my body, but it's no use. My body is dead weight, ready to obey Grisha's command. I feel like crying, but the tears won't come. I march on to the front lines.

(Levi's POV)

I wake to the worst pain ever. Tears run down my cheeks as the pressure in my stomach increases. I feel my baby shifting inside of me and I cry out as the pressure worsens. Hanji throws open the door and rushes over to sit beside me. Erwin joins us in the room and Isabel comes in too. She widens her eyes as she sees my stomach.

"Who knocked you up?" She asks.

"I told you already dear. Eren knocked him up. Remember, we bet on it."

Isabel nods and goes to sit on the other side of the bed. I grab her hand and squeeze it tightly. Hanji puts her hand on my stomach and closes her eyes.

"The baby's coming." She says. "Erwin, go get me my bag. It's downstairs." He nods and disappears from the room. "Isabel, you need to help calm him down."

"Hanji…I'm only eight months." I say through my heavy panting. "Why is the baby coming now?"

Hanji sighs. "Rivaille, the baby isn't premature. I know it might seem like it, but this baby is ready to come out."

Erwin comes back with Hanji's bag in his hands. She quietly thanks him and shuffles through the contents. She pulls a scalpel from her bag and lifts up my shirt.

"Are you ready to cut the baby out?" She asks me.

I gulp. "As ready as I'll ever be." I say then wince at the pressure the baby is putting on my stomach.

"Isabel, hold his shoulders down. Erwin, hold down his legs." Isabel braces her hands on my shoulders and Erwin pins my legs down to the bed. Hanji hovers the scalpel over my stomach. She digs the blade into my flesh and cuts the flesh. A scream rips from my throat and I try to move away, but Isabel pushes down on my shoulders. Hanji finishes cutting open my stomach. She bends down and I feel her fangs digging into my womb and ripping it open. My head feels dizzy and I shriek at the pain in my stomach. Blood runs down my hips and my thighs. I weakly try to struggle, but feel my vision fading and the noises around me becoming shrouded in darkness. I vaguely hear my baby's whines and Hanji calling my name before the darkness pulls me under.
