Secret Souls, Passionate Hearts

Chapter 1: Not the Type to Vanish

Isabella's POV

I never thought Ferb was the type of person to vanish. Well . . . until it happened.

Ferb had always been cool, calm, and collected, and he talked sparingly, knowing that about 85% of what humans say is simply irrelevant.

When Phineas and I were eleven and Ferb was thirteen . . .

It was just him and his step-brother Phineas, sitting under the tree in the backyard. Then came me, Isabella. I moved in across the street a short time after Ferb and his father moved to America from Britain.

When school started, we met Baljeet and Buford, and we met Django and Irving last summer. There are a lot of us now, but it all went back to the two of them under that tree.

Nine years later . . .

At the end of graduation, Phineas and I were looking for a home for the two of us, and when we came back to ask his opinion on something, he was just gone.

The room he'd shared with his red-haired step-brother was half-empty. All of his stuff was gone. Only his bed remained, the sheets pulled up and tucked neatly at the corners, a sign that he hadn't slept there in a while. There was no note, no warning. Nothing. He was just gone.

Phineas always tried to laugh and smile like he always did, but I could see him sit and stare into space when he thought I wasn't looking, missing his other half.

Three years later . . .

Phineas and I are engaged. We have been for nearly two years. We keep putting off the wedding, hoping Ferb will come home.

We try to stay optimistic, but it's been so long. Phineas is getting worse every day. Tomorrow is December 1st. The winter holidays are coming soon.

Phineas is staying late at the office tonight. He's cooped up there, and he won't tell me why.

He came home with tears of happiness in his eyes. Ferb wrote an email to his office box. The two of us spend the evening reminiscing about the times the three of us shared.

No POV

"There's something about the winter holidays that makes me all sentimental," Isabella said to her fiancé a week before their new-found holiday, Chanukah, a combination of Hanukah and Christmas, made especially due to their separate religious backgrounds.

"That's funny, Izzy. I was thinking the same thing."

"Nearly everyone's sitting down all snuggled up together. Baljeet and Ginger, Gretchen and Jon, Buford and Adyson suddenly are all cosy-cosy, Candace with Jeremy, Stacy with Coltrane, Pinky met another chihuahua, even Perry met another platypus." Isabella smiled at the two of them curled up on the floor in their nest, where Perry Jr. lay sleeping and another egg ready to hatch the coming spring.

Phineas put his arm around her and smiled, then looked sadly into his lap. "Everyone but Ferb."

"Yeah, whatever happened to him? One day, he just seemed to disappear without a trace."

"I managed to connect with him long enough to invite him to Chanukah, but we have no way of knowing if he'll show."

"If he does, he'll be welcomed back with open arms. I just wonder what he's been doing all these years, Phin. What would cause him to move so much, without any ties to back home?"
