Hi guys! Rather overwhelmed by the amount of attention this hasn't gotten both here and over on AO3! I know MPreg and Teacher/Student isn't for everyone so very happy that everyone seems to be enjoying it :) Here's the chapter some of you were waiting for... Enter Sebastian!

Thursday morning brought around another battle between Blaine and Baby trying to make him throw up everything he had eaten the previous day when he went to brush his teeth. He quickly crept into Cooper's bathroom and took some of his brother's mints. Just the thought of the way his toothpaste smelt was enough to make him heave all over again. Maybe later we could let Daddy brush his teeth, huh Baby? Can you do that?

The twenty minute walk to school was over far too quickly and Blaine found himself standing outside the main entrance to the school. He reached into his pocket and popped two more mints into his mouth, just to freshen his breath again. He leant against the wall next to the doorway, taking a deep breath and feeling his body tense up. He really didn't want to sit through all his classes today. Maybe he could just skip and sit with Kur- with Mr Hummel. Or just go to his class, maybe no-one would notice.

Blaine was seriously considering it when Principal Sylvester walked past him, sneering something about juvenile mini-gays and being late to class. Blaine bowed his head and walked through the front doors, forcing a smile onto his face. He spotted Tina talking with Jake Puckerman and he headed for them, waving, but as he got closer and closer he realised some-one's perfume wasn't mixing well with another smell in the busy hallway and he bypassed Tina and Jake, fighting the overwhelming feel of nausea, and headed straight for the bathroom. Oh, please Baby. Why can't you give Daddy a little break?

But, apparently, Baby didn't fancy being cooperative in the slightest and Blaine bumped into some-one that was blocking the doorway to the boys bathroom, his stomach almost in his mouth, he swallowed his excess salvia and continued to fight to need to vomit. Blaine faintly heard his name being called and some-one grabbing his shoulders and practically pushing him into the room next to the boy's bathroom. The Teacher's Restroom.

Kurt stood outside the bathroom, after shoving Blaine inside, making sure no-one else would disturb the boy. Tina had followed Blaine down the hallway and had watched the exchange. She approached the door, and Mr Hummel, "Sir, is Blaine okay?"

Kurt knew Tina was very close with Blaine, in his short time at the school he very rarely saw Blaine without Tina or the Evans kid between classes, but he didn't know how much Tina knew. He shook his head and ushered her inside the room after checking how empty the hallway way.

Blaine wondered how many times he was going to come close to throwing up on his teacher before he actually did it. Blaine wiped his mouth and stood up, leaning his back against the stall door, before quickly bending back over the toilet again.

This is not fun, Baby; I'm never going to be able to get anything done if you keep making me feel sick. I promise I will not make you sit through awkward family dinners with people we don't know if you just play nice with Daddy now. Please?

Tears escaped from the corners of Blaine's eyes as he continued to take deep breaths. He heard the main bathroom door open and then a tentative voice that he recognised as Tina's. "Blainey?"

Oh no… Blaine bent, once more, over the bowl and heaved the last of his stomach's contents into it.

"You okay?"

Blaine hadn't locked the stall behind him after he had entered the bathroom and Tina was now watching him with his head shoved down a toilet emptying his guts out.

"Clearly not. Shut up Tina." Blaine would have laughed at his friend, answering her own question, but his breath was coming in sharp and heavy trying to get his body back under control. Blaine heard something drop the floor and then he felt some of his wayward curls being pushed back from his damp forehead and her free hand rubbing Blaine's back in circular motions.

"Anything I can do to help?"

"No, I'll be okay in just a minute." Blaine leant his head on the forearm that was still gripping the edge of the toilet.

They waited, together, in silence, to see if Blaine was done being sick and when Blaine slumped backward, resting his back against the steel divider, still in front of a crouching Tina he smiled at his friend "Thank you, T."

"It's okay. Feeling any better now?" Tina was staring at Blaine, her brow crumpled in concern.

"Better. Not okay though." Blaine paused, "really not okay."

"Need to talk?" Tina knew something was wrong with Blaine, she'd never seen that look on his face, even on the first day he had transferred to McKinley he had put on a courageous front and made fake jokes until he felt comfortable enough with his new set of friends to put a real smile in place.

"I need you to promise this stays between us. Only two people know so far." Blaine's voice was completely devoid of emotion, and it was scaring Tina.

"Ok."

"Serious, T, no-one. Not Sam, not Unique. No. One." Blaine finally made eye contact with her, a steely look in his eyes that Tina had never seen before. Tina took the hand that was lying limply over his knee and threaded her fingers through his, squeezing reassuringly.

"I promise, Blainey-days." She smiled, trying to ease her best friends tension.

"I'm pregnant." Blaine rushed the words out like if he spat them out then it wouldn't be as much of a shock.

"Ohmygod. Ohmygod. Ohmy. God." Tina was practically hyperventilating which amused Blaine for a short period before he squeezed the hand still held in his.

"Breathe. It helps." Blaine felt very tired all of a sudden. He really wanted to nap, just to curl up in Mr Hummel's class and listen to the soothing tones of his voice whilst she slept. He wondered if he could ask him for that one day, just talk whilst he power napped for a little while.

"Have you told Sebastian?" Tina was stunned. Nothing about this was good. "What are you going to do?" Oh, just so bad. "Oh, what did… Have you told Cooper!?"

"Slow down T. I haven't told Seb. Yet." He sighed. "I'm keeping the baby and Cooper flipped out for about an hour the other night. Just. Lots of yelling."

Blaine didn't know how long Mr Hummel had been in the bathroom for, he couldn't remember if the door shut straight after Tina had come in, but he knew he had been there since Blaine had confessed to Tina, at the very least. The two friends were silent for a while, just holding each other's hands and Kurt knew he needed to get them moving before someone came along.

"Mr Anderson, Miss Cohen-Chang. I'm sorry, but you two do have class to get to."

They both climbed to their feet and Blaine watched as Tina blushed a little when she realise she was now in the bathroom with two men. Two gay men, but, one of them being their teacher clearly made her a little uncomfortable. Kurt slipped back out of the doorway as soon as he heard them begin to move, knowing they would be out shortly. He hadn't meant to intrude on them but the only way to lock the bathroom was from the inside, and he doubted either of them knew that, and he couldn't risk anyone finding them.

Kurt handed them both passes that he had filled out to give their teachers to excuse them for being late to first period. "Please make sure you're in for the rest of the day." Kurt aimed it mostly at Blaine before heading off to his own classroom.

Blaine hugged Tina close, whispering his thanks to her, he took a deep breath and, before he lost his courage, "Will you stay close, at Lunch I mean, when I tell Seb?"

"You're going to tell him today?" Tina looked around at the empty hallway before whispering "Here?"

Blaine sighed. "I need to do it soon otherwise I'll keep avoiding it and it'll be even worse." Blaine wasn't looking forward to it at all but he knew Sebastian couldn't be the last person to know. News, and gossip, travelled fast at McKinley and he didn't want someone that might have overheard them or saw him racing to the bathroom to get to Sebastian before he did.

"I'll be there. Promise."

Blaine watched as his best friend walked away to her class, trusting in her words, before swallowing repeatedly realising, once more, that everything in his life really had changed.

Kurt had only had to interrupt the friend's conversation in the bathroom because the textiles teacher, Chandler, had come barrelling down the hallway and begun to talk to Kurt, in the empty hallway, very loudly and very inappropriately. Kurt had managed to get him to leave when he had made an excuse about curry the night before and pretended to need the bathroom very desperately. He didn't want the two in the restroom to overhear the way Chandler was propositioning him. When Kurt had, unintentionally, overheard their conversation he felt himself smile. He was glad Blaine was telling some-one else so the teen would have some-one else on his side too. Nothing about the coming months was going to be easy and he would need as much support as possible.

He had gone to his classroom, after letting Tina in to the bathroom, and gave his first period students a pop quiz to scramble over before rushing back to stand guard outside the bathroom. He had grabbed the passes on his desk and a pen before leaving the room so he could fill them out whilst he waited for them.

It was now almost fifth period which meant it was Lunch time and Kurt found himself worrying about Blaine all over again. He had a niggling doubt in the back of his mind that he was forgetting something and that something had to do with the boy. Shit.

Kurt pushed himself away from his desk and looked out of his window to see Blaine sitting in the courtyard, looking around for someone, he assumed Sebastian. Kurt could see Blaine's leg bouncing up and down; he smiled at how adorable the young boy was. Blaine looked better, at least from Kurt's vantage point; he had a lot more colour to his face and didn't look quite so seasick. Kurt let out a breath, he wasn't aware he was holding, He's okay, no need to worry, get back to marking Hummel.

Kurt watched as Blaine looked up toward the other side of the courtyard and forced a smile onto his face as Sebastian sauntered up to him. Tina rubbed Blaine's should and walked away to another table, close enough for Blaine to be able to see her but far enough that the couple had their privacy. Kurt narrowed his eyes as the smirk fell from Sebastian's face as he loomed over Blaine's small form and grabbed Blaine's upper arms with his hands.

Blaine and Tina weren't talking about anything in particular; Tina was just kind of filling the time whilst she waited with Blaine for his boyfriend. She was trying to stay as calm as possible so that she wouldn't alert Blain as to just how worried she really was about the whole situation, let alone how Sebastian would react.

"T, I can practically feel you vibrating. Please, don't panic. If you panic I will and then I might throw up again." Blaine put his hand over Tina's on the table and squeezed once before pulling back and placing them in his own lap.

"Sorry. I'm just, anxious I guess." The brunette smiled apologetically at her friend but further comments were halted when she heard Sebastian call out Blaine's name from across the courtyard.

"Here we go." Blaine mumbled under his breath before smiling up at Sebastian, motioning him over. "Hi Seb!"

"Hey Blaine. Asian girl that's always with my boyfriend." He shifted his eyes over to Tina, never hiding his contempt for the girl that he had to share Blaine's attention with. "How's my favourite boy?"

"Lovely to see you too Sebastian. I've gotta run." Tina was up and gone before Blaine could even try to stop her or even say goodbye. Thanks for the support Cohen Chang.

"What's up hot stuff?" Sebastian wasn't stupid, despite popular opinion, he knew Blaine had been avoiding him the past few days so he was hoping that Blaine would spout some rubbish, he'd be the consoling, and reassuring, boyfriend and hopefully lunch would end in him getting off so he could relax in his last few lessons.

"I'm pregnant." Wow, heck, don't sugar coat it Blaine. Go for it!

"Excuse me?" Sebastian was floored. Involuntarily he sank to the seat next to Blaine, disbelief over his face.

"Pregnant. Me. I'm, um, pregnant."

"I heard you the first time." Sebastian hissed, "We used condoms, Blaine. Every. Time. Fuck. No. No way, this shit isn't mine."

"Condom's aren't 100% effective, Seb, and you're the only person I've ever… been with."

"Shit. Blaine, I've got my College interviews coming up. I've got fucking Princeton after me. What the fuck are they going to think when you rock up as my partner looking like a fucking beached whale? No. No, Blaine. How could you do this to me?"

"To you? I'm pretty sure I'm the pregnant one Sebastian!" Blaine felt his anger begin to rise, along with his boyfriends.

"It's Princeton Blaine. I'm not giving that up because you're some freak of nature!"

"Freak of- God. Sebastian, is that what this is to you? Is that what I am!?" Blaine was so furious with Sebastian's selfishness that he was almost spitting.

Sebastian got up to his feet, fuelled with anger and disappointment; he reached over to Blaine, grabbed his arms and hauled him up to his feet, his grip tight and painful around Blaine's biceps. "How could you, Blaine. I'm not fucking losing my College over this. This pregnancy is your fault. Your shit to deal with."

Blaine's eyes widened in fear as he realised Sebastian had raised his voice, all eyes in the courtyard were focussed on the arguing pair. Sebastian still held Blaine's arms in his hands, shaking him, and tears filled Blaine's eyes.

Kurt had taken the stairs down to the courtyard almost three at a time, afraid of how violent Sebastian was going to get with the smaller boy. Kurt forced authority into his voice and dropped it to a tone he very rarely used.

"I suggest you remove your hands, Mr Smythe. Now."

Slowly Sebastian released his hands from Blaine, dropping him back down to his feet and Kurt watched as his tears began to flow, hunching his shoulders over and allowing the sobs to wrack his small frame.

"Mr Smythe, go and see Miss Berry. Don't move until I get there."

Kurt was furious. He never believed that violence was an answer to anything and he felt his hands forming fists at the side of his body, angry at how someone could even think to threaten some-one as kind hearted as Blaine. He watched as Sebastian left the courtyard. Kurt didn't dare look down at Blaine until he got his own temper under control, not wanting to cause the boy any more worry or stress.

Kurt squatted down in front of Blaine, by the table side, "Are you okay?"

"No," Blaine said simply, looking up at Kurt, tears sliding down his cheeks making his face blotchy with colour. His eyes were red, Kurt could see the heartbreak in them and he felt his own heart constrict in response.

"It's okay sweetheart. I'm going to get Tina to take you home. Is that all right?"

Blaine simply nodded and Kurt motioned Tina, who had made her way back over almost as quickly as her teacher once she saw Sebastian put his hands on her friend, over with one hand gesture, not taking his eyes away from Blaine.

"Miss Cohen-Chang, could you take Mr Anderson home please. Stay with him, I'll excuse you both from classes for the rest of the day."

"Thank you Mr Hummel." Tina sat down beside her best friend and leant her head against Blaine's shoulder and put her arm around his small waist. "C'mon, Blainey-days. Let's got home."

Kurt stood there, watching the two friends leave, realising that what he was feeling wasn't standard between teacher and student and that Sebastian Smythe should keep a clear distance, from him and Blaine, for a while.
