A/N: Thanks for the reviews everybody . Sorry it took so long to finish.

The next day, Abby and Hoagie went back to the hospital because they received an urgent call. When they got there they went up to the doctor. The doctor didn't look too happy.

"Mr. and Mrs. Gilligan, we originally called you to ask you if we could do more surgery to Chelsea to try to remove the rest of the cancer," the doctor said grimly, "However, on your way here, she…she stopped breathing. Chelsea Gilligan dead."

All is lost. She is gone

She'll never again see her home

Her mind is trapped in a cave

Abandon Ship. There are flames.

Jump off the boat? Are you insane?

Now we're lost forever, underneath broken waves

"D-dead?" Abby gasped, "No, she can't be. She's too young to die! No, NO!"

Hoagie embraced his wife but was too shocked for words. Chelsea can't be dead, he thought. But she was.

The couple went home with tears in their eyes. Their only daughter was gone forever. She had lost the battle and the war against cancer.

They told their friends and Chelsea's friends. All were shocked at the news but they were prepared for this outcome. Still they couldn't believe Chelsea was gone.

"She-she died?" Daniel gasped when he found out, "Numbuh 25 died!"

"Numbuh 25?" Nigel frowned, "Are you okay, son? Her name is Chelsea."

"Chelsea, Chelsea. That's what I meant," Daniel blushed, "I just can't believe it…"

Kuki cried her famous Sanban tears when she heard the heartbreaking news. Wally embraced her as much as he could but he couldn't take away the pain that everyone felt.

Their children, Jason and Olivia, were both devastated. They were only 10 years old and they lost their best friend.

"Chelsea Gilligan, a girl who fought against brain cancer for so long, has just died in Cleveland General Hospital. She leaves behind her parents and best friends," said the news reporters.

Nigel turned off the television and put his head in his hands. It had been only a day since Chelsea died, yet it seemed like an eternity. Doctors confirmed Chelsea dead from Astrocytomas and brain malfunction. Her funeral was set for that Saturday which was only 2 days away.

In the KND, Jason, Daniel, and Olivia were allowed a month off with no missions. They were even offered to be able to skip decommissioning when they were 13 so they could remember Chelsea. There was a memorial service at Moonbase for Chelsea the day before her funeral. Every operative came to offer their condolences. Everyone suffered from the loss of Numbuh 25.

But no one suffered more than Hoagie and Abby Gilligan who lost their only child, their only daughter, the reason for their existence, their life, and now she was gone…
