Santana was sprawled out on Blaine's bed, a growing pile of empty tissue boxes surrounding her.

"Do you want to talk about it?" Blaine asked tentatively, dodging a piece of tissue as she threw it in what she vaguely remembered to be the direction of Blaine's waste paper basket.

Santana shook her head. "I really don't. I'm an idiot." She sighed, sitting up right with some effort. "I'm pretty sure I just single handedly ruined my relationship with Sebastian. So now I've doomed myself to be a single teen mom."

Blaine blinked at her. "I don't think I heard that right. A single teen mom?"

Shit. "Oh yeah, I'm also an idiot who got herself knocked up."

He sighed, allowing himself to flop heavily onto the bed beside her. "Not going to beat about the bush; you're an idiot. Let me finished!" He added, as Santana moved to interrupt him, her mouth shutting with a loud clack.

"You're an idiot, yeah. Not for the pregnancy thing, although that's going to be fun to explain to parents who have just come to terms with the fact that their daughter is a lesbian."

Santana rolled her eyes. "If you have a point, Blaine, please hurry up and get to it. I'm about five seconds from throwing this tissue box at your head."

"Right, sorry. You might have done something stupid, really stupid judging from the state you're in. That doesn't mean you're going to lose Sebastian. You love him and I'm pretty sure he loves you too. You need to talk to him. Without getting all Snixx about it."

She nodded. "That would be good advice, were it not for the fact I threw a bowl of popcorn at his head. I missed!" She added defensively when she noticed his horrified expression.

"I still think you should talk to him. In public. Where there are witnesses to stop you doing anything potentially illegal. Like putting someone in hospital with a bowl of popcorn. You don't want to be giving birth in prison."

Santana shook her head, tearing at the piece of tissue she had in her hand. "My cousin, Sofia, went to jail a couple of years ago, nothing serious, just unpaid parking tickets. She gave birth in jail. Said it was awful. She only just got the poor kid back."

Blaine nodded, his expression carefully blank. "So, you're going to talk to Sebastian?"

Santana sighed, meeting his eyes for the first time since she'd arrived. His mom had been quite alarmed to find a sobbing girl on her doorstep demanding to see Blaine. He probably had a lot of explaining to do when she left.

"I could set up a meeting, tell him what I know about the whole picture incident."

Santana narrowed her eyes. This couldn't be happening. The one person she had trusted the most with everything going on in her life with Sebastian and he was now telling her that he had information about the picture incident. Had he ever been planning on telling her? "Blaine, what are you saying?"

"Don't look at me like that. It wasn't me. I wouldn't do that to you, either of you. I was just as surprised as you were. I just think I might know who's behind it. I say might, I'm about ninety percent sure I helped make the whole thing possible without even realising it."

Santana stood, pacing as she tried to process what he was saying. He'd kept this from her. He'd promised he'd known nothing. Now here he was admitting that he probably knew who was behind it. That he'd made the whole thing possible. "Why didn't you say anything?"

"I wasn't sure, I didn't want to accuse anyone without being certain I was right."

She picked up the tissue box, tapping the corners with her index fingers. "I can't believe I trusted you. I told you everything. I was honest with you, I forgave you when you didn't have my back in glee and this is how you repay me? I knew you were still upset about your eye and I get that, I'd have been out for blood too, but I can't believe you would use me."

"I didn't!" Blaine protested, his tone both hurt and defensive. "I wouldn't!"

"But you did, without even realising it! Do you know how much this has hurt me?"

"Would you let me explain? Please, Santana."

She nodded, sitting in the corner, as far from him as she could manage. "Explain."

"A few weeks before regionals, Puck came up to me. He was asking questions about the warblers, about Sebastian. I accidentally let slip that Trent had told me that Thad has a bit of a crush on Sebastian."

"What does that have to do with anything? Really though, Thad?"

Blaine shrugged. "Apparently. Anyway, Puck asked me if Thad was upset that Sebastian was with you. I laughed at that, obviously the poor guy's going to be upset if the guy he's got the hots for is suddenly not only in a relationship but in a relationship with a girl. Puck seemed really interested after that, came with me to visit the guys over at Dalton. I didn't question it, I probably should have but I'd rather have Puck on side."

Santana nodded. "So you think he convinced Thad to help him sabotage our relationship. Do you think Thad would have agreed?"

"Thad can be quite intense when he likes someone. He was really over the top when he liked me. He wasn't Kurt's biggest fan, used to tell me that my covers were better than the originals. That sort of thing. It was a bit much, I didn't realise at the time; I just thought it was flattering. He got over it pretty quickly, he was really upset when Kurt left Dalton. Then again, Puck can be pretty persuasive."

"You're telling me."

"I'm going to text Sebastian, ask him to meet up with me to discuss this. You can come if you want."

Santana nodded. "Are you going to warn him that I'll be there?"

Blaine chewed on his lower lip. "I think it might ruin our chances of getting him to show up."

"I just don't want him to think that I'm trying to ambush him."

Blaine smiled sadly at her. "Don't worry, I'll tell him it was my fault, that I didn't know that you two were arguing so I invited you both. He can't get upset with you for that, can he?"

Santana nodded, still not altogether that thrilled with Blaine's plan. She knew that Sebastian was going to be pissed with her. Still, she needed to see him. She wanted to apologise, she'd been a bitch and she wanted to make things right, no matter what. She owed that to them both.

xXxXxXx

Sebastian was sat in the Lima Bean, reviewing his European history assignment. He hadn't been able to focus on anything since his fight with Santana and it was pretty obvious when he was reading his work back that his mind had been on anything but European history.

"Sebastian!"

He looked up, pushing away his notebook as Blaine came and sat down opposite. "Hey, Blaine." Sebastian felt all the wind leave his lungs as he realised who Blaine had brought with him. "Santana. What are you doing here?"

"Blaine invited me."

Blaine looked between them, eyebrow raised. "I didn't think you'd mind. Apparently, from the way you two are looking at each other, I was wrong. Is everything alright here?"

Sebastian looked at Santana, her dark eyes pleading, before turning his attention back to Blaine, forcing a smile. "Absolutely. Want me to get you anything to drink?"

Santana shrugged her jacket off, sitting awkwardly next to Blaine. "You know my order," she whispered, her voice barely audible as she looked down at her lap.

He nodded curtly, turning his attention to Blaine who smiled gratefully. "Medium drip." He held some cash which Sebastian immediately turned down.

"I should've remembered that. Hey, don't bother, it's on me."

"Let me help you carry them back," Santana offered, apparently feeling more confident.

"It's three drinks, Santana, I'm sure I can manage." He regretted his harsh tone as soon as the words were out.

She nodded, smiling quickly in Blaine's direction. "Right, of course. Thanks."

As he stood in line for the drinks, Sebastian found himself listening in to the conversation at the table. He only caught snippets but it was enough to tell him what he'd already suspected. Blaine knew. He knew everything that gone on between them. He paid the cashier for the drinks, telling her to keep the change before going back to the table.

"Here you go," He slid the drinks across the table, holding his own tightly between his hands. "So, why'd you bring me all the way down here?"

Santana looked to Blaine before nodding. "Tell him."

Blaine sighed. "I think I might've been involved in the whole photo fiasco. Tangentially. I didn't even realise until the night before last."

Sebastian raised his eyebrow, taking a swig of his coffee. Flinching as he realised he hadn't given it long enough to cool. "You might have been involved?"

"There's about a ninety percent chance."

Sebastian breathed out, allowing himself a quick glance in Santana's direction. "We trusted you. Why would you be involved in trying to break us up?"

Blaine's eyes widened. "I didn't know I was. I've been thinking back on a conversation I had with Puck a couple of weeks before it all happened. He seemed very interested in Thad's crush on you."

Sebastian could feel a blush creeping onto his cheeks as he realised Santana was watching him. "I didn't encourage it," he muttered, realising what Santana was silently accusing him of. "It was innocent enough. Are you saying you think Thad was involved?"

"I think he might've helped Puck without realising. I know I did. Puck can be very persuasive when he wants to be. All Thad needs to have done is send the picture in Puck's direction. He needn't even have realised it was a big deal."

Sebastian nodded. "If they were talking about parties or something-"

"Thad might've brought up the graduation party for Wes and the prank kiss," Blaine finished. "Puck need only have asked for proof and Thad would've just sent the picture. He's always hated being accused of lying."

Sebastian narrowed his eyes. "Why would Puck go to all that trouble?"

"I told you, he was trying to get me back in his bed."

Blaine frowned, look at Sebastian. "He's not clever enough to think of this by himself. It feels too personal anyway. The idea of Sebastian cheating on you. It's almost like they were trying to give you a taste of your own medicine." He turned to Santana who was looking almost green.

Santana gasped. "I think I'm going to be sick." She stood up rushing to the bathrooms.

Sebastian half stood to go after her. "I don't understand."

Blaine smiled. "That's just morning sickness. Don't worry about that. I was saying. I think someone wanted Santana to know what it felt like to be betrayed by someone she loved. To know what it's like to be cheated on."

Sebastian nodded. "You think it was Brittany?"

"No, I think it was someone who cares about Brittany and was mad with Santana when she wouldn't be."

Sebastian stared blankly confused.

"He means Artie."

Santana sat down next to Blaine, taking a long drink of her coffee. "Artie's been in love with Brittany for ages. I should've known. He'd do anything to make up for the time he called her stupid. This would have been the perfect opportunity. It wouldn't be the first time he's worked with Puck to do something stupid."

Blaine nodded, clearly remembering the punch bowl incident from the prom the year before. "What do you think, Sebastian?"

He frowned. "I think you might be onto something."

Blaine pulled his coat on. "I think I should go have a word with Artie and Puck. I'll leave you two to talk."

Santana opened her mouth to object.

"He's right," Sebastian cut in. "We really do need to talk, not just about this." He looked at her pointedly.

A/N I made an extra-long chapter. Yay! Looks like things may finally be starting to sort themselves out for these two. Ha, more angst is sure to come, because I'm terrible!
