I'm so glad you guys liked the first part to my story! Hopefully I can jerk some tears ;) I connected this story to an older one of mine, adding a few little tidbits in there relating to it! Humor me and see if you can guess which one it is...

I do not own Big Time Rush.

The outside weather was freezing, chilling Kendall to the bone before he walked into the glass building they would be performing in. The staff and crew of the museum had cleared out all of the valuable exhibits on the lower floor to make room for the band to play. Even though Kendall was seriously worried for Carlos' health, he had to admit he was thrilled.

Ever since Kendall was old enough to play a chord on the guitar he had always wanted to visit the Rock and Roll Hall of Fame. His father always called him Daddy's little rock star.

And now he was playing a concert there.

Spotting the stage, the blonde band member made his way downstairs, looking over the setup. James stood at the foot of the stage, cappuccino in hand as he read over the set list they would be singing. Logan was on the stage, bending down to check the wiring to the amps behind the microphones. That was one of Kendall's pet peeves, Logan always having to check their perfectly fine sound system. But he just tried to ignore it. Kendall was especially excited because he had gotten to bring his acoustic guitar, or as he liked to call it, 'His Baby' along to play.

As Kendall slipped off his gloves and pushed them into his coat pocket, he looked around for his sick friend. He was nowhere to be seen.

"Fuck," Carlos groaned, wiping his mouth on a piece of toilet paper. Staring down into the toilet, he became disgusted, seeing it filled with the vomit he had just regurgitated. Not really caring at the moment, he laid his head against the ceramic bowl, closing his eyes in pain.

"I have to sing, I have to sing..." he repeated to himself over and over as his hands gripped the sides of the toilet, helping himself to stand upright. No matter what anyone said, Carlos was the most determined out of all the members of Big Time Rush, and it showed.

But it wasn't for the reasons some might think. No, it wasn't for the screaming and adoring fans. It wasn't for his own self pride or to make his parents proud of their high school drop out son.

It was to impress Kendall, to show him how committed he was to their team, their brotherhood. They were the four musketeers, and they didn't care who said there were only three.

Leaving the small restroom stall and walking tiredly over to the mirror, Carlos examined himself for the second time that day, not being pleased with what he saw. He was still pale and sickly looking, but he hoped the crowd would be too focused on the music to notice. He should be lip sync-ing today, but he isn't. He never will.

Straightening his hair up, Carlos ventured from the bathroom to find his friends getting ready to jump onto the stage. The museum had already let the fans in, and as soon as they spotted Carlos walking from the bathroom, they began to wail and scream his name. He smiled weakly, the loud and harsh noise hurting his ears tremendously. One girl attempted to leap over the ropes to get at him, but the body guards pushed her small body back.

"Carlos man, where were you?" Logan asked as their Latino friend finally joined them backstage. Kendall gave a sigh of relief, seeing his pal looking a little better than before.

"I was peeing," the olive skinned man replied shortly, grabbing his earpiece and pushing it into his right ear. Logan seemed to buy it, shrugging his shoulders and looking forward, humming the words to one of their new songs excitedly. Kendall glanced over at Carlos, seeing the shorter man grip his stomach candidly, his expression turning into a wince for a split second. He would have said something, if the announcer hadn't shouted over the loud speaker that it was time for them to enter stage right.

Plastering on a fake smile, Carlos bounced onto the stage with enthusiasm, pointing and waving as he peered out into their sea of fans.

He made it through the first three songs with no problem, his pain seeming to subside for the time being. Carlos was actually having a good time now, stepping and swaying to the dance routine they had practiced the night before in the tour buses' small living room area. It probably would have been a humorous thing to watch, what with James' long lanky arms and legs taking up at least half of the area.

Then it was time. Kendall walked to the side of the stage to retrieve his pride and joy, his guitar. Carlos smiled, remembering the time he and Kendall had sat together on the blonde's back porch in high school after one of their big games. It was the first time he had ever heard anything Kendall had originally written. The first time they had kissed.

As Kendall began to strum the tune to the song on his instrument, Carlos closed his eyes, only for a moment, to get the feel of the acoustic rhythm. It was beautiful, the melodic strum of the guitar soothing to Carlos' ears. But when the Latino opened his eyes, readying himself to sing the first line of the song, it all went wrong.

The stage's bright multi-colored lights began to fade in and out of Carlos' vision, the crowd's roaring sound growing smaller and smaller. He seemed to panic, and turned to his side to reach out for Logan, but his surrounding world went in slow motion, his eyes finally rolling into the back of his head. With what little Carlos could hear, the sound of Kendall screaming was all that was left as everything went completely black.
