A/N: Sorry this chapter took so long to upload. Anyways, Enjoy!

"Boy, that sure didn't take long. I thought her house was farther away." Phineas gulped nervously as he looked up at the front door. "Well, I'll have to wing it, I guess." He slowly raised a hand, knocking on the door. A few minutes later, the door opened up, revealing a woman on the other side. She beamed at him.

"Phineas! Come in!" She ushered him inside, showing him into kitchen. "I'm sorry, but I'm afraid Katie just stepped out. She came home, changed and then just left." The woman opened up the door to the oven, taking something from it. "Would you like a homemade brownie? I just made them myself."

He smiled. He'd missed Mrs. Millhouse's cooking. "Sure." He took a bite, then after a few seconds, swallowed. "Uh, Mrs. Millhouse? Do you have any idea where Katie might have gone?"

"Oh! Have you two reconciled?"

"Um…no."

"Oh." He winced.

"I'm sorry Mrs. Millhouse. It's just—"

"Oh don't worry about it Phineas. I know how it is. It's understandable." She walked over to the kitchen sink, gazing out the window. "Now let me see…she didn't say where she was going, but normally when she takes off, she goes to the Fireside Girls clubhouse."

He stood up, brushing the crumbs off his shirt into a nearby trashcan. "Thanks Mrs. Millhouse. I should probably be going. Oh. And thanks for the brownie."

"Anytime Phineas. Now you just run along now." She ushered him out the front door and just for the sake of it, he jumped off the porch, clearing the two short steps in one go.

That was easier than having to talk to Katie. Maybe he should just do that all night instead.

About twenty minutes later, Phineas came across the Fireside Girls clubhouse. He stood outside it for a moment. It was smaller than he remembered. Of course, he was seventeen now and much, much taller than he had been at ten. He absently measured himself from foot to head.

Yep. He was going to have to squat to get inside. Slowly, he squatted down, alternating between hopping and wiggling his way to the door. He knocked. "Katie? Katie, are you in there? Uh, I'd come inside, but it's a bit small for me now. Of course, you're older too, so I don't think you can really fit in there, but…well, girls are usually shorter than boys—"

A giggle was heard next to him. "That's why I sit outside the clubhouse."

"Oh thank goodness." He uncurled his legs from underneath him, sinking to the ground. "I was wondering how I was going to—oof!" He fell backwards as Katie tackled him to the ground.

"Oh Phineas, I miss you so much. Why'd you have to leave me for Isabella?"

"Um, Katie?"

"I know I'm not Isabella, but…we had something, didn't we?" She let him go, helping him sit upright. Her eyes searched his. "Please Phineas, tell me that it wasn't a mistake."

His heart lurched. He had forgotten how beautiful she was. He took in her appearance: a simple brown blouse with a pair of jeans and tennis shoes. Her blonde hair was tied back in a ponytail. He absently lifted a hand to brush a strand of hair from her face, only to shake his head. No. He couldn't do this. "Katie…"

"Phineas please, don't leave me again."

"Katie…" he took her hands in his, looking her square in the eyes. "Katie, I did like you. I liked you very much. And I enjoyed dating you. I mean, we had fun right?" She nodded. He smiled. "But…I only liked you. Isabella I…well, love."

She started to cry.

"Aww. Please don't cry. Come here." He scooted closer to her, wrapping an arm around her shoulders. "Katie, I didn't want to dump you. I didn't want to hurt you. But…I can't date both you and Isabella. It would be wrong."

"I-I know. But…"

"Hey, there is nothing wrong with you. I like you just fine. You know, as a friend. At least, I hope we can still be friends." He lifted her chin up so he could look in her eyes. "My heart belongs to Isabella. You know that."

She nodded, the sniffles subsiding. "I guess I just didn't want it to end." She studied him. "You really love Isabella, don't you?"

He smiled as the image of his girlfriend popped into his mind. "Yeah, I really do." He paused. "How could you tell?"

"I can hear it in your voice when you talk about her."

He smiled again, standing up and dusting himself off. He offered her a hand. "Come on, I'll walk you home."
