Summary: "I'm sorry I need to leave, but I think that we both need time, so I'm leaving for the city where I can forget it all." Only one problem, what city is that? And Phineas has to find her, or lose her forever.

A/N: While I am on a roll tonight, I might as well continue writing this story... The more chapters I get done tonight means that there are less chapters to write later on down the road.

Anyway, to recap where we ended up: Phineas had Isabella's memories stolen from him in the middle of Lhasi... Will he get them back? I don't know... Read and find out.

I do not own Phineas and Ferb. All © goes to Dan Povenmire and Jeff "Swampy" Marsh.

Chapter 10: A New Home Development

After ten minutes of desperate searching came up to nothing, Phineas decided to call home and say he couldn't help Isabella anymore. Phineas picked up his cell phone and dialed up Ferb who would just be getting ready for school.

*ring* *ring* *ring* "Hello?" Ferb's voice came up on the other end.

"Hey Ferb," Phineas said a bit shakily. "How's it going back home?"

"Oh fine..." Ferb sighed.

"What happened?" Phineas asked, almost forgetting his issue entirely.

"Mom and Dad found out that a robot of you has taken your place and asked where the real you is. I said I didn't know... Mainly because I didn't... Where are you now?"

"Lhasi, Tibet," Phineas said automatically. "Did you tell them what I was doing?"

"Yeah," Ferb admitted. "It was the only thing they would believe that you would do, although they think you are still in the country and not overseas."

"Okay, so... sounds like you have your hands full over there," Phineas said dejectedly.

"Hm?" Ferb replied. "What's wrong?"

"Well the first thing that's wrong is that you are talking soo much in this conversation its actually starting to get creepy," Phineas said "the other thing is that I lost Isabella's memories in Lhasi... So even if I did find her, there is no way that I could give her her old life back.."

"Do you really think I would let you leave without making sure that you could find Isabella's memories if you lost them?" Ferb asked.

"Guess not... so what do you have?" Phineas replied, curious.

"GPS tracker on Isabella's memories, not so much that box you put it in," Ferb explained. "The GPS tracker is almost microscopic and really sort of stuck there forever, so you won't lose it.."

"Thanks Ferb," Phineas said, relieved. "Can you send me the coordinates so that I can start tracking it down?"

"Yep," Ferb said before clicking a few buttons. "Information sent to you, so your GPS tracker should be tracking it now."

"Okay thanks," Phineas said, pulling out his GPS locator and seeing where it was in relation to him. "Okay, I have it locating... Thanks Ferb."

"Oh and Phineas, do you really think you'll find Isabella in Lhasi?" Ferb asked.

"Nope, I haven't found a single clue for her here... So I'm going to go get Isabella's memories and go head back to Shanghai. I need to pick up her trail before it goes cold again."

With that, Phineas closed his phone and ran off in the direction of Isabella's memories.

A/N: Well Phineas is certain he went the wrong way... Ferb helped Phineas find Isabella's memories... we can all start moving on again :) Only Phineas doesn't realize that he went the right way to begin with, so that's bad...
