They brought Mabel into the hospital room to see Dipper where her adoptive fathers and the doctor were waiting.

The sight of her brother in a hospital bed with all these tubes and wires and looking so sick nearly brought Mabel to tears, but she trusted herself to be strong as she went to his side.

"Hi, sis," Dipper managed.

"Hey, bro-bro." Mabel gave Dipper a hug being mindful to not accidentally hurt him. "What happened?"

Dipper looked sadly at Stan and Ford. The older men were about to explain the situation to her, but Dipper stopped them. "Let me tell her."

Dipper figured that his adoptive fathers have had to break so much bad news to them over the years, Dipper could at least spare them this one. "Mabel…my kidneys are failing."

Mabel felt her whole world crumble around her. Just this morning, Dipper had been fine. Well, not exactly fine, but he was just a little sick. He just needed some soup and bed rest, like when he used to get sick at home. Now, just a few hours later she was being told that his kidneys were failing. She didn't exactly know what kidneys did, but she knew they were important.

"What…what does that mean…? Are you gonna…?" Mabel bit her lip unable to say the horrible word.

Dipper wished he could tell her he wouldn't. All he could say was, "It's curable."

"Oh! Thank God!" Mabel cried tears of joy and gave her brother another hug. He winced in pain, so she had to pull away. She couldn't wait to get him well so that she could hug him again.

"Mabel…" Stan put a hand on her back.

Dipper shot Stan a warning look. He didn't want Mabel to donate her kidney to him, so he didn't want her to know.

"She needs to know, Dipper," Stan said reading the boy's mind.

"Know what?" Mabel asked.

"No, she doesn't," asserted Dipper.

"Dipper, we have to tell her," Ford added.

"WILL SOMEONE PLEASE TELL ME WHAT'S GOING ON?" Mabel screamed, quite put up with everyone dancing around the subject.

Stan took a deep breath, "Pumpkin, Dipper needs a new kidney and well- "

"Give him mine," Mabel said without hesitation. She turned to the doctor and lifted her shirt. "You can do it right now! Make Dipper better again!"

The doctor smiled. How precious that the child didn't even question it, but she still needed to understand the process better. "We aren't quite ready to do that yet, dear. This is a big surgery, so it's going to take a lot of work and planning on everyone's part so that it goes smoothly so that both you and your brother can go home."

"But…" Ford interjected. "We haven't decided on anything yet."

"What's there to decide? Dipper's sick and we need to help him!" She addressed the doctor again. "I'm his twin, so I'll be the best match, right?

"That's correct."

"We just want to explore other options, sweetie," said Stan.

"Why? If I'm his best match, then what option could be better? Why won't you let me help him?" Mabel asked as she looked up at Stan with those big brown eyes that melted his heart.

The doctor bent down and put his hand on Mabel's shoulder. "Donating a kidney will take a toll on your body."

"I can handle it! Grunkle Stan says I'm the toughest girl he knows! What do I need to do to show you that I can?"

The doctor was amazed at how this girl didn't even seem to care what would happen to her. All she cared about was helping her brother. But he wanted to make sure she understood what she was signing up for. "I recommend eating well and getting lots of exercise over the next few weeks, so your body will be able to handle the surgery and recovery better. You'll be living with one kidney from now on, so having a healthy lifestyle will be important."

"No problem! I'll think, eat, and sleep health! It'll be good for me to stay in shape anyway, so I'll be ready to start cheerleading in the fall!"

The doctor's face fell as he glanced over at Ford and Stan who hugged their daughter tight knowing what she was about to hear.

"I'm afraid it won't be a good idea for you to cheer in the fall Mabel, this is a major surgery and well…your body will be different afterward."

"So I'll have to take a year off? Well, that sucks, but I'll come back to the squad with a vengeance next year!"

The doctor felt awful that the poor girl didn't fully understand. "Mabel, going through with this surgery means it won't be safe to exert your body too much anymore. You'll have to give up cheerleading and other strenuous activities…for good."

Dipper felt his heart sink as it finally dawned on his sister what she'll have to sacrifice. "Mabel, you don't have to this. We can find another way." Dipper tried to assure, but he began coughing violently from exerting too much strength himself.

Mabel shook at the sight of her brother needing all this help and equipment just to breathe properly. It wasn't fair that she would have to give up cheerleading, but it was even more unfair that her brother had to suffer like this. She would never forgive herself if anything happened to him, especially since she had the power to make him better.

Mabel stared at Dipper for a long moment before she asked the doctor, "But if I don't do this, Dipper might…?" She couldn't bring herself to say the D word. "Might not get better?"

The doctor simply nodded.

Mabel took and deep breath and steeled herself. "Then that settles it. I'm doing this."
