"What are you so happy about?" Blaine asked Rachel as she practically danced into the kitchen. She could understand his confusion; after all, she was normally only like this when New Directions had won a competition or when Finn had taken her out on a particularly well thought-out date.

Now, however, neither of those were the case.

"Kurt's coming over for a sleepover," she informed him, rummaging through the fridge in an attempt to find the food she'd prepared earlier. "We're going to have a musical marathon, a diva-off…"

Blaine didn't look impressed. "You do that nearly ever week," he reminded her, and Rachel's rummaging came to a halt. She extracted her head from the fridge and stood upright, glancing somewhat confusedly at her slightly younger half-brother.

"You're right," she muttered. How had she never even thought about that before? The previous year, the sleepovers she had with Kurt (and sometimes Mercedes, and even less often Tina) had only taken place about once a month. This school year, however… like Blaine pointed out, those sleepovers occurred just about every week.

Blaine just shrugged and went back to eating whatever he was eating; Rachel looked at it in distaste. "I thought you didn't even like the guy that much?" he eventually asked, when Rachel's head had disappeared back in the fridge.

"Yes, I do," she countered. "He's my best friend, Blaine. Plus, having so many sleepovers is a good thing. Next year, we'll be in New York, and we'll probably be roommates. This is an excellent way to practise for that."

Blaine scrunched up his face, as if not believing that someone would willingly share a room or even an apartment with Rachel. "Sure," he muttered.

Rachel rolled her eyes. She was glad that Kurt came over virtually every weekend for another reason: it gave her the chance to avoid having to spend the whole weekend with Blaine. Yes, she knew that, in reality, Blaine wasn't that bad to have for a brother; he was definitely cleaner and less loud than most guys she knew – apart from Kurt, of course. The fact that Blaine was gay was definitely a plus too.

They had known each other their entire lives, but Blaine had only been living in Rachel's house (in the weekends; he boarded at Dalton throughout the week) since this school year. Something about his mother's new boyfriend being homophobic, or something. Therefore, it had not been a surprise for Rachel when her dads had decided to take Blaine in.

She'd just managed to find all the food and the drinks in the fridge and taken them out when the doorbell rang. Hastily telling Blaine to stay away from the food – even though it was less than two feet away from him on the table – she raced towards the front door.

"Hey, Kurt!" she greeted her friend happily. Barely waiting for a response, she dragged him inside. "You can bring your stuff upstairs, if you want. Here, I'll help you." With their combined strength, the two managed to get the suitcase upstairs, and Rachel wondered for a moment how Kurt had even gotten the thing into his car in the first place. Oh, right – he must've somehow blackmailed Finn into helping him.

"Come on," she told him. "The food's still downstairs. You're early, and Blaine distracted me." That seemed to catch Kurt's attention.

"Oh?" he asked airily. "Blaine's here? I thought he boards at Dalton?"

Rachel eyed him confusedly for a moment. "No, he's always here during the weekends. You know that, Kurt."

He smiled a little uneasily, but followed her downstairs nevertheless.

"I didn't eat anything, I swear," Blaine told her before she could even open her mouth (which was a feat, but again, they'd known each other their entire lives, so Blaine had had plenty of time to perfect that particular ability).

Rachel picked up a few items. "Good. We would've made you watch musicals with us all night if you had."

Blaine rolled his eyes. "Oh, yeah, now I'm scared. You know I love Broadway musicals just as much as you two, right?" Glancing from Rachel to Kurt, who was still awkwardly standing a couple of feet behind Rachel, he said, "Alright, scratch that, I probably don't. But I still love them."

"Yeah, yeah," Rachel said dismissively. "Kurt, can you take the rest of this upstairs?"

Kurt was next to her within seconds. "Of course," he said. "Hi, Blaine." Rachel frowned; he sounded a little off. She hoped her friend wasn't coming down with something, as it would put quite a damper on their sleepover. And on his ability to sing, of course. And if it was contagious, on hers as well.

Blaine smiled. "Hey, Kurt," he greeted him, nodding his head slightly, and… did Kurt just let out a breathy laugh or did Rachel mishear? On their way out of the kitchen, he almost stumbled, something Rachel knew he only did when he was nervous. Standing still and letting Kurt go upstairs before her, she looked back into the kitchen, but it was just Blaine sitting there. When he noticed her looking, he raised his eyebrows at her expectantly. Rachel just shrugged and followed Kurt upstairs.

"Are you okay?" she asked him when she entered her room. He seemed rather flushed, now that she looked closer.

"I'm fine," he insisted, nodding furiously, and now Rachel definitely knew something was up.

Instead of questioning him, though, she decided to let it go for now – but she was going to interrogate him more about the subject tonight. First, however, they were going to watch West Side Story.

Letting her thoughts drift away as she watched, she suddenly remembered what Blaine had been telling her earlier. "Hey," she said, sitting up. "Kurt. Have you realised that we've been having a lot of sleepovers lately? You're here almost every weekend."

He stared at her, wide-eyed, and coughed. "What – no, I hadn't. Now that you mention it, though…" He laughed nervously. "Um. Is that a problem?"

She shook her head. "No, of course not. I didn't realise it either before Blaine mentioned it today."

"Oh?" Kurt shot her a quick glance before looking back at Rachel's ceiling. "What did he say?"

Meanwhile, Rachel's brain was working overtime. "Nothing, really," she replied carefully. "He just didn't get why I was so excited to have you over since you come over all the time."

Now, she could also see Kurt's mind reel. "Right," he muttered softly, wrapping his arms around himself. "Excuse me for a moment." He almost bolted up from her bed and out of her room. She heard the bathroom door slam shut two seconds later, and she was almost inclined to follow him and see if he was alright. Maybe he did have a stomach bug. She couldn't really think of anything else that could be wrong.

Unless…

No way. There was no way. Rachel's eyes widened and she looked from the spot on her bed where Kurt had been just now to the doorway. It seemed impossible, but… it was the only other explanation.

And now that the thought was planted in her head, she couldn't believe how she hadn't seen it earlier. All the nervous looks and smiles and laughter, the way Kurt seemed to always be all but speechless around her brother and the fact that he always insisted on having all the sleepovers at her house now that Blaine lived her as well…

"You're in love with Blaine," she accused when she heard the door creak slightly, indicating that someone was coming in.

A dry laugh, and Rachel's heart plummeted. "That would be very narcissistic, Rach, if I were in love with myself."

She could only stare at Blaine. To make matters even worse, that was the moment Kurt returned from the bathroom, and it was obvious that he'd either been crying or trying hard not to cry. Or both. It was probably both.

"What's wrong?" he asked obliviously, glancing from Rachel to Blaine – and okay, how had Rachel never noticed her friend's very obvious attraction to her half-brother before? It was practically written all over his face.

"Nothing," she said hastily, only to find herself echoed by Blaine. "Blaine was just… leaving, right, Blaine?"

"Yeah." Blaine coughed awkwardly. "Bye, Rach. Kurt."

Kurt looked after him just a moment too long for it to be normal, but in the end, he closed the bedroom door anyway. "What was that all about?" he asked Rachel, sitting down on the bed next to her.

Deciding that now was not a good time to either confront Kurt about his feelings for Blaine, or to admit that she'd practically told Blaine that Kurt liked him, Rachel just smiled at him winningly. "It was really nothing. He just came to complain about the fact that the movie's too loud."

If Kurt didn't believe her, he didn't mention it.
