Ferb paced quickly around his living room. His mind refused him sleep after Django's call. After the surprising message, Ferb requested him to come over as soon as possible.

'I can't believe it worked. I just…I can't…believe…it worked. Marie will be absolutely thrilled!' Vanessa crossed her arms and stepped in his path to get his attention.

"Ferb, honey, what's wrong? You didn't come back to bed after that call and you haven't spoken at all this morning." She placed a hand on his cheek.

"I'm getting worried." Ferb sighed and placed a hand over hers.

"I..I need you to trust me on this. I don't want to tell you until I am fairly certain of the outcome."

"Ferb…" She eyed her husband questioningly. A screech of tires and an impatient horn outside surprised them both. Thomas sped down the steps, device in hand. Ferb quickly kissed her and headed out the door.

"Django's waiting. I promise I'll explain later." Vanessa sighed as the door closed.

"You better."

"You mean it really worked!?" Thomas stared incredulously at the supposedly faulty device. He didn't question his father when he was told to be prepared for Django's arrival, although their destination and purpose were unknown to him until they were barreling down the road. Django nodded at his question.

"I can hardly believe it myself. When I got back to the center, the pig showed no improvement. After a couple of hours, she actually got up and played with the piglets. By the time I called your dad, she was as active as a sugar-high toddler. We did a reading on her vitals and they were completely normal." Thomas scooted to the edge of his seat to look at his father.

"We have to tell Marie!" Ferb smirked as they pulled into the Flynn driveway.

"We know." All three jumped from the car and raced to the door. Ferb knocked on the door rapidly. They jumped when the door opened.

"Marie!" Phineas popped around the door, surprised by the company.

"Uh…no, she's in the backyard. What's wrong?" The three anxious guys looked at each other, clearly surprised by him answering the door. Ferb spoke first.

"Well, Marie wanted us to update her on how Django's pig was." Phineas raised an eyebrow. Django jumped in.

"Yeah, the pig wasn't doing well yesterday, so Marie was upset. I've come to tell her that she is okay." Phineas smiled and stepped aside to let them in.

"If you say so." A collective sigh passed between the bunch and they made their way inside towards the back door. As Ferb passed, Phineas grabbed his arm, signaling him to stay. They watched Django and Thomas head out the back. They walked over to watch the group through the window. Marie was sitting under their only tree, staring off in despair. As the guys approached, she slowly looked up at them. Phineas sighed and turned to his brother.

"What's really going on?" Ferb cleared his throat.

"What do you mean?"

"Ferb, my daughter has been upset since I brought her home yesterday. She's barely spoken, which means it's a very prominent problem and I want to know what it is."

"We told you. Marie's upset because she believes she failed to help Django with his pig. He's here to tell her otherwise." An awkward silence hung in the air as the brother's eyed one another. Ferb gulped, knowing that Phineas knew that this wasn't the whole truth. He also knew, however, that he wasn't the one to tell him what the truth was. After a while, Phineas spoke rather lowly.

"So, how is the pig?" Their attention returned to the group outside. Marie was returning from the garage, blueprints in hand. Her smile had finally returned. Ferb smiled.

"She's doing well. Her vitals are back to normal. It just took a little time." Silence fell once again. Ferb heard Phineas' breathe hitch and saw him walk off out of the corner of his eye. He watched his slowly heaving back, seeing him wipe his hands across his eyes.

"So that's it. She actually did it, didn't she?" Ferb wrapped his arm around his brother as he continued.

"I…I've tried…so many times before…but she actually…" Phineas looked up at Ferb, rubbing away the tear trails on his face.

"What does she need to finish it?" Ferb smiled and squeezed him in a sideways hug.

"Just believe in her. She's come this far; she'll complete it." Both turned and observed the determination that now replaced her melancholy.

'So the delay is approximately 12 hours, which means…' Marie's mind raced as fast as her pencil did across the blueprint, increasing factors in her equations and testing their results theoretically. Thomas watched over her shoulder incredulously. Fifteen minutes ago, she looked as if she had given up on everything, now she had more spirit than ever. He looked over to her face, a slightly amorous smile spreading.

'She's back.' He jumped out of his thoughts when she suddenly turned to him.

"Does that seem logical?" He glanced back to the forgotten plans. All of her equations were changed by factors of 4, leaving all operations of the device effective and non-lethal. Thomas nodded.

"Of course. Should you have increased the factor anymore, then you would be doing more harm than good. I would lower the voltage here, though. That would put a lot of strain on the device. Just add the difference to the exposure time and you would get the same effect." Marie nodded and changed the equations as instructed. With Thomas' approval, she grabbed the device and began the adjustments. Thomas turned to Django, whose mouth hadn't closed since Marie had grabbed the blueprints. Django shook his head out of its stupor.

"Seems like you've got things here. I was never good at the tech stuff, so I'll get out of your hair." He slumped back to the house, still stunned by their genius. Thomas suppressed laughter and turned back to Marie. Her hand shook as she fumbled with a screwdriver, determined to move the screw at the end. The aggravated look in her misty eyes told him that she needed this done. He walked over behind her and, placing his hand over hers, forced her to turn the screwdriver the other way. Marie looked up at him, eyes wide with surprise. Thomas blushed slightly and mumbled, averting his eyes.

"If you can't even do that, maybe I should take over." Marie blinked, still in shock from his "help". She glanced back at the device in thought. Smiling gently, she passed them over to him. Thomas took them, gently set the device on the work bench and began where she left off. Marie tilted her head curiously as she watched him, his cheeks still a little pink.

'He's helping me like always. If it wasn't for him, I wouldn't have gotten this far. I…I…' She felt a lump develop in her throat and, without thinking, fell forward. Thomas' blush intensified as he felt Marie's face bury into his back. Her arms wrapped around him and her hands clutched the front of his shirt.

"M-marie, what…?" He stopped when her body started to shake, feeling wet dots through his shirt.

"Tommy…I…I…thank you…so much…" Thomas smiled softly. He placed the device and screwdriver down and turned in her arms, hesitantly hugging her.

"I-it's nothing. You shouldn't have to do this alone. I wouldn't…couldn't let you." Marie looked up at him, his eyes averted once again. She wiped her eyes and giggled at his embarrassment. Leaning on her tip toes, she planted a light kiss on his cheek.

"Thank you." His face turned a new color of red. He quickly spun around and restarted working.

"L-like I said, it was n-nothing." Marie smiled as he fumbled with the screwdriver. She sat in the chair beside him and waited for him to finish. After a few minutes, Thomas sighed and held the device up for Marie to see.

"Finished." Marie jumped up and grabbed the device, eying it as if it were made of gold. Finally smiling, she pulled him into a quick hug, and then dragged him back to the house.

"It's finished!" Those words left her mouth as soon as she entered the door. Phineas, Ferb, and Django all turned their attention to the children. Marie walked over to her father and showed him the device.

"This is going to help me bring Mama back." Phineas looked silently at the device, then his daughter. Pride overcame him as he wrapped his arms around her.

"I knew you could do it." He pulled back and smiled at her.

"You got your perseverance from your mother." Marie blinked in surprise.

"You…knew about this?" Phineas nodded.

"Let's just say a little birdie told me." Marie looked to Ferb and Thomas, both of whom shrugged in ignorance. Phineas chuckled.

"Since you've worked so hard, how about a little break before the big finale? Mr. Slushy Dawg sound good?" Marie bit her lip and looked down at the device, wanting to put it to immediate use. She felt her father's hand on her shoulder.

"That can wait, after all…" he pulled out the cell phone, "…you've got all the time in the world!" Marie chuckled at his corny joke and placed the device on the counter.

"Then what are we waiting for?" Django stretched and cleared his throat.

"I'll head back to the clinic. Sis can't handle all those animals for long, despite what she thinks." Everyone filed out of the door and headed out towards their destinations. By the time Phineas and Marie dropped off Ferb and Thomas, it was already dark.

"Geez, time sure does fly when you're having fun, especially with your uncle." Marie giggled.

"I can't believe you guys built so much out of Slushy Dawgs. No wonder the manager asked you to build something to attract customers." Phineas shrugged.

"Eh…" As they pulled into their driveway, Phineas cleared his throat.

"I just want you to know, Marie, that whatever happens, I'm still proud of you. I know your mother would be, too." Marie stared at her father for a while before smiling. She leaned over and wrapped her arms around his neck.

"I know, Daddy." She pulled back and bolted out of the car and into the house. Grabbing the phone and device, she ran up to her room. She pulled out her picture box, picking out her newborn picture. She turned on the phone and was shocked by what she found. Along the bottom, an app with a speech bubble flashed. She pressed it and watched as a single message popped up.

'Ferb told me what you are doing.
Good luck, baby girl!
3 Aunt V'

Marie closed the app with a smile.

'This is it!' She chose the T.T. app and hesitated as the satellite popped up. Taking a deep breathe, she spoke.

"Go to Danville Memorial Hospital, eleven years ago, June 3rd, 11:30p.m." She closed her eyes as the beam scanned her body.

The sterile smell of the hospital hall alerted her to her arrival. She glanced around the hall, looking for the appropriate room.

'209, nope. 210, nope. Ah, 211.' She stared at the door ahead of her, taking as deep a breath as she could. With shaky hands, she silently peered in the room.

The first thing she noticed was the figure in the corner; her father laid back in the chair, sound asleep. She could faintly her him snore, but not over the heart monitor. Its pauses between beeps let her know that she didn't have too long to linger. She entered the room, moving passed the small bassinet to where her mother lay. Holding the device against her chest, Marie felt her resolve weaken a bit.

'What if this doesn't work? She looks so pale…I don't know about this.' She felt herself backing down. As if sensing her distress, the phone vibrated lightly. Vanessa's message popped up, offering its encouragement. Marie stared at it in awe, replaying what her father had said before she left.

'They believe in me, so I need to believe in myself.' Taking another deep breath, she pointed the device's scanner at her sleeping mother. Glancing over to the bassinet, she smiled and pressed the button. The red beam ran up and down her mother's figure several times, each time filling Marie with hope. After several minutes, the device powered off, signaling its completion.

'Now, to wait and see.' Marie watched the heart monitor intently. The pauses, however, remained the same.

'Maybe it takes more time.' Her focus set on her mother, hoping to see a change in her appearance. She returned her attention to the ever slow beeps of the monitor. Suddenly, she heard soft whimpers coming from the bassinet.

'Oh no, please, me, don't wake up!' When the whimpers became louder, Marie silently ran for the door. As it creaked to a close, she heard cries from her younger self. Footsteps soon followed, as well as soft murmurs of comfort. Marie sighed.

'That was close.' She walked further down the hall, observing the device in her hand.

'I guess it didn't work.' She hung her head low and pulled out the phone. She swallowed the lump in her throat and ordered the phone to take her home. In a flash, she was gone.

Phineas peered out the room, the sudden flash startling him.

"Guess it was a glitch in the lighting, huh?" Marie sniffled in response and began whimpering. He closed the door and returned to rocking her, singing the lullaby he remembered his wife humming earlier. Soon, she was back to sleeping soundly. He gently placed her in the bassinet and returned to his seat in the corner. He observed his wife, slightly concerned at her paleness. He jumped when he heard her take in a deep breath, holding his own. The heart monitor went silent for a moment.

Marie dropped the phone and device on the floor of her room, not caring if they broke. She climbed onto her bed and buried her head in her pillow.

'It didn't work. Why…why didn't it work?' She began to sob into her pillow. She couldn't take it anymore.

'I give up. I let everyone down. I…can't do it.' She heard a soft knock on her door, followed by her father's voice.

"Marie, are you okay? What happened?" She buried her face deeper into the pillows.

"I don't want to talk about it. Please, just…leave me alone." She heard the door open and footsteps approach her bed. She hugged the pillows closely, refusing to look her father in the face. She felt the bed lean down slightly as he sat.

"I don't want to talk about it." A tender hand pushed some hair behind her ear and grabbed her by the arm, pulling her gently into an embrace. She clenched her eyes shut as she cried into a warm chest. She felt a hand run through her hair, something her father never did. Her eyes opened wide as a soft, calming voice began to hum her lullaby. She pulled back, staring at the chest of the one who comforted her. Since when did her father wear pink? Slowly her eyes drifted upward. Teary blue eyes met comforting dark blue, a new, yet familiar face. Marie felt her chest bubble and lunged at her comforter.

"M-m-mama…" She cried happily into Isabella's chest as her mother wrapped her in another lovingly embrace. Phineas walked over and placed a hand on Isabella's shoulder, happy to see his family complete again. Marie pulled back and looked up at her mother. Isabella wiped the tears from her eyes and ruffled her hair, smiling proudly.

"That's my girl."
