The Omega returned to his room, a little fazed by the fight he just witnessed and the fact Jean just sort of decked Reiner, someone who looked double his size. He felt a little hot and sweaty, running his hands through his hair. When Eren returned to his room he found Armin sitting nestled in the corner of the room. Eren was still a little shaken He felt hot, sweaty and his clothes felt itchy on his skin. He wanted to strip but he supposed Armin wouldn't appreciate him streaking. He shuffled into his room, collapsing on his bed.

"You look restless." Armin stated, looking up from where he was buried in his nest.

"I kinda just saw Jean punched a pregnant Omega. I guess I'm just shaken up because of instincts." Eren mumbled into his pillow. Armin immediately became alarmed and pushed himself up, waddling over to Eren.

"Who did he punch?" Armin asked.

"Reiner." The blond male paled and rushed out of the room as fast as he actually could. It left Eren confused but he shrugged it off. Something Omega related probably. He pulled his shirt off, fanning himself with his hands in a poor attempt to lessen the heat. He was sweating so much it was ridiculous and he also had this weird feeling in his stomach that was building up. He sighed and dumped himself on the bed, running a hand through his messy hair. He knew in the back of his mind what was actually happening and reluctantly he got back up off the bed, beginning his hunt to find Hanji.

Armin was huffing by the time he reached Marco's room. Partially due to his stomach and partially due to the fact he was in no way fit. He knocked on the door, while trying to catch his breath.

"Come in." A muffled voice came from behind the door and Armin opened the door and moved inside. Marco was positioned on the bed, pillows piled up behind his back and head dipped forward.

"Marco are you okay?" Armin asked as he waddled over to Marco's bed. The freckled covered male hummed in response, shifting himself slightly on the bed.

"Just having some pains." Marco explained, watching as Armin sat down on the edge of the bed.

"What kind of pains?" Armin questioned, running his hand over the soft skin of Marco's shoulder in an attempt to soothe him. He averted his eyes and ran a hand over his stomach.

"Labour pains…maybe." He mumbled, knowing far too well that Armin was not going to be happy with him.

"Why are you still here then?! Marco!" Armin scolded, hitting him gently. The blond gathered himself so he could move off the bed but Marco grabbed the sleeve of Armin's shirt.

"No!" He yelled, pulling back Armin back down onto the bed, "If you tell them then they'll get Jean and I really don't want to see that dick's face right now." He grimaced as another contraction washed over him.

Armin sighed and situated himself in a position so he could rub Marco's back and hole his hand at the same time.

"You're just jealous, aren't you?" Armin stated, wincing at how hard Marco was squeezing his hand.

"He slept with another Alpha! I'm sure you wouldn't be happy if Erwin slept with say…Eren or something." Marco retorted, reaching down to stroke his swollen belly.

"You know Jean didn't choose to do it. Marco, come on. Plus, Erwin would never have to sleep with anyone. He chose me especially." Armin replied, stroking Marco's back with both hands, trying to time out the contractions in his mind. It wasn't Marco's first pregnancy but it was his first labour. He ran his fingers through the other Omega's hair and sighed softly.

"Marco. Just don't shut Jean out again, please?" Armin pleaded, "You know how much he cares about you and with your last pregnancy I think he at least deserves to see his children be born." He looked down at Marco and smiled softly.

"Why are you always right?" Marco sighed. His gaze flickered back onto his protruding stomach.

"Should I let your dad come watch?" He asked, running a finger along the soft skin. In response he got a very strong contraction that left him groaning low and squeezing the sheets in his fists. Armin talked him through it, whispering soothing words of encouragement in Marco's ear.

"A-Armin?"

"Yeah?"

"I think my water just broke."

Armin wasted no time in calling the medics, who reached Marco in a matter of minutes and swept him away to the hospital facility. Jean had been contacted, a requirement when Omega's waters had broken and it had begun a waiting came to see if he would actually show up. They let Armin stay beside him as he went through his contractions, providing a hand to squeeze and ear to listen to Marco screaming that Jean was the fucker that did this to him. Currently he was asleep, face distorted in pain as he shuffled his position. Armin sat in the chair next to the bed, a book in his hands that one of the nurses had gotten for him. He was reading aloud to his unborn child, giggling when he stopped and received a kick.

"Naughty boy," He laughed, earning another light kick. He ran his fingers along his clothed stomach.

"I hope you at least like me." Armin sighed. Four more months and he was allowed to leave this place, as long as his son was born without any complications. After he left he could hopefully track where his first child had gone. She would be eight now, if he had counted correctly.

Jean came skidding around the corner, smashing through the door, startling Armin.

"Is Marco okay?!" He exclaimed earning a glare and a sharp 'shh' from Armin.

"He's sleeping, be quiet." He warned, shutting his book and placing it down on the nightstand.

"What's happening? Where's he up to? Oh god?! Have the babies been born yet? Did I miss it? Fuck." Jean whispered, running his hands through his hair, leaving it sticking up haphazardly.

"Calm down. He's was about five centimetres dilated last time they checked so you got here in time. Could have been here a little early, though." Armin explained, giving him a dirty look. Marco mumbled something in his sleep and let out a soft groan, bringing Jean's full attention to him. The Omega/Alpha scurried over to him, taking his hand in his own and placing the other on his mate's stomach.

"He looks like he is so much pain." Jean muttered, placing a kiss to Marco's temple.

"He is and you're going to go through this too." Jean noticeably paled at that but his features twisted in pain as Marco squeezed his hand tightly and sat up in one fluid motion.

"I-I have to push." He groaned, body clenching up as another contraction seized him. Armin nodded, hurriedly moving to the door to alert one of the doctors. The lady with dark hair that was monitoring Marco earlier took another look as Marco squirmed in pain.

"That was…fast," She stated, scratching her head. Marco's screams brought her back out of her thought and she moved into a better position to help the birth.

"I need you to push on the contraction." She ordered, "Also would the father like to come over here a see this?" Jean nodded enthusiastically, repositioning himself to see in between Marco's spread legs. He fainted before the baby had even started to crown.

When he awoke, he was slung over the chair listening the cries of babies. He blinked a few times before he remembered where he was and immediately jumped up. Marco was sat up in the bed, one baby that was attached to his nipple, another on the other nipple and one resting between his knees.

"Finally back to the world of the living?" Marco laughed softly, gesturing him to come closer.

"Wow…they are just so…great. They're just great." Jean said, picking up the child between Marco's knees. He placed a kiss to their forehead, feeling himself tear up.

"That's Ymir and these two are Mina and Sasha." Marco stated, readjusting because Mina had finished feeding but Sasha was still going at it.

"Marco, I'm so sorry." Jean said, rocking Ymir in his arms. She was staring up at him, more like glaring at him, her face still red.

"It's okay, Jean."
