Chapter 1

The day he came is one they would never forget. He brought out things in them that had never been seen before and probably wouldn't have ever been seen if not for his presence.

It started with the phone call. The one that had changed many things, just as he would...

"Blaine?" Kurt's questioning voice filled the silence as he paused in his packing, sounding a little surprised at his boyfriend's lack of response to the shocking, he was sure, bit of information he had just given him.

Wide hazel eyes rose to meet his before a cute crinkle appeared on the handsome face as Blaine's rather distinctive brows furrowed in thought. "I'm sorry... I think I—did you just say you have a twin?"

A small laugh bubbled through his lips as he shook his head and turned his focus back to packing. "Yes."

Blaine's warm hands on his paused him in his actions once more. "An actual twin—as in someone who looks just like you?"

"Yes," he repeated while nodding his head slowly before pausing when he saw an odd look of interest flash over Blaine's face. "Just so you know...even though we are technically monozygotic it's not like we are absolute carbon copies of each other. The last time I saw him, Carson was—"

"Carson?" Blaine repeated with interest once more. Was he over his shock then?

"Yes?" he asked with an arched brow as he gently pulled his hands free and turned back to the clothes he had been packing.

"With a 'C' or a 'K'?" his boyfriend asked with sudden amusement in his tone.

"With a 'C'. I don't think I've ever seen it written out as 'Karson'," he commented with a small shrug of his shoulders as he pulled out a pair of jeans he had just packed and refolded them.

"It would have matched with Kurt—well, kind of," Blaine pointed out as he crossed his one leg over the other to scratch at his bared ankle lightly.

"My mom named me, thinking it was cute that it rhymed with Burt. My dad picked Carson," he explained, sighing and rubbing the back of his neck as he tried to think of what else he might need.

"Heh. I can see that...it fits," Blaine answered with a fond laugh.

Looking to his boyfriend he blinked, not understanding. "Did I miss something?"

"Come on... Car. Son?" Blaine waggled his brows pointedly. "With your dad being a mechanic..."

He just stared at him for a few seconds before rolling his eyes and taking a small step back. "Oh my God. You've been around Finn too much."

Blaine just laughed at that, infectiously so until it made him smile lightly.

"I can't wait for you to meet him. It should be an...interesting experience. At least it was when Carson met Finn," he spoke up after a few minutes of silence, stretching his arms before checking through his bag.

"I can't believe you never mentioned him before now. I mean not only is he your biological brother but a twin?" was Blaine's answer as the shorter boy caught his hands once more and tugged him over to sit next to him on the bed.

He allowed it, chewing on his lip once more before sighing and leaning back on his hands. "No one outside of family, besides Carole and Finn, really know about him. As much as I love my brother he's a bit of a...not really a secret or anything, it's just kind of hard to explain. Well, it was when I was a child, and then it just kind of became habit."

"What do you mean?" he was asked lightly as Blaine shifted carefully to face him more fully.

Taking a deep breath he let it out slowly before lifting his eyes to meet patient hazel. "The way I understand it is when my mom died, her parents thought it would be too much stress for my dad to take care of two kids by himself and wanted Carson and I both to go stay with them for a while. My dad obviously didn't agree with that so they argued to take one of us at least for a little while. I didn't want to go, so Carson did. It was supposed to be only for a bit while my dad coped. Then school started and Carson wanted to stay to attend there. My dad and grandparents then agreed that Carson would come home for the summer and he did for a few years, but then he got older and wanted to stay with his friends. So my dad and I would go out to visit him. After a while it became just the holidays."

Silence fell over them after he stopped speaking, swallowing thickly a few times to moisten his now dry mouth. When Blaine started rubbing his arm in a comforting gesture, he gave him a small smile of thanks and decided to continue.

"Now with the death of my grandparents and Carson actually coming back home...I just—I never really mentioned him because I guess he kind of became like a cousin or an uncle or something. You know...family, but not really mentioned unless for a purpose and wow! That sounds really horrible!" he groaned with a small frown, crossing his arms.

"What sounds really horrible?" a new voice suddenly asked, startling himself and Blaine to the point where they both jumped a little. Looking over to his doorway he saw it was Finn.

"I was just telling Blaine about Carson," he explained while subtly bringing a hand to his chest.

Finn's brows rose at that information before lowering slowly in what appeared to be distaste. "Oh. Him."

"Him?" Blaine's questioning voice barely hid his burning curiosity as he looked between the two step-brothers.

He opened his mouth to explain but Finn beat him to it.

"He's evil. I swear," the taller boy replied seriously in warning.

"Finn! Carson is not—" he tried to defend one brother from the other only to be cut off when Finn raised a hand and spoke over him.

"Evil," Finn repeated in an annoying stage whisper before starting to walk away only to pause as he seemed to remember something. "Oh yeah. Your dad said to hurry up with the packing. He wants to leave soon so he's there to help with the funeral when needed."

"Right!" he replied while moving back to his bag and checking it over once more. "Almost done."

Blaine watched Finn leave before getting to his feet and looking around, probably trying to figure out if there was anything he could help with. "Do you have everything?"

Doing another quick mental checklist, he found he was basically done, other than needing to make sure to grab things like his wallet, keys, phone, and garment bag with the suit he would be wearing for the funeral. Zipping his bag closed he nodded. "Yeah. The funeral is tomorrow and we'll be staying a couple of days longer after that."

A small smile formed when he felt warm arms surround him in a comforting hug, Blaine's chin moving to rest on his shoulder. "And then you'll be back home."

"And then I'll be back home," he agreed before laughing with a hint of mischief. "And you'll be seeing double."
