Sarah had built herself a time machine. It was a device that could take her backwards in time as far as she wanted. Though there were millions of possibilities for how she could use it, she only wanted it for one.

Unfortunately, it only altered time, not space. If Sarah wanted to be in the heart of the attack all those months ago, she would need to be there when she travelled. If she used her machine in the Ranger Base, she would only transport herself back in time to the Ranger base. From there, she would have to head out and find her father.

Ironically, time was not a luxury she had. If she wanted to keep the present intact, she would need to ensure her presence in the past created no ripples. She couldn't be seen by anyone who would recognize her and she couldn't alter what was meant to happen. She was simply travelling back to watch.

"Are you ready?" she asked Mick as they stood on the construction site. It had been the location of a popular plaza, where those who worked in the nearby office buildings would come for lunch. Since the attack, it had been nothing but rubble, and had only just recently been cleared out so they could rebuild.

"Ready," he nodded. She set the time and date. She knew exactly when to set it because her eyes had been glued to the news during the attacks as she watched the devastation. She received up to the minute news on everything regarding the absolute worst day in her life. "You?"

"Hold onto it," she said and turned the machine on. It took a minute to work, and Sarah worried in that time she had made a miscalculation, but suddenly, she found herself in the center of the attacks, staring up at a giant Galvanax while everything around her was falling apart.

"Run!" Mick shouted and grabbed her as the ceiling right over their heads started to collapse. They dove out of the way, barely escaping. The screams heard behind them indicated not everyone had been so lucky. Sarah glanced back, but Mick grabbed her arm and started to pull her along, "He wasn't in there. I didn't see him."

"Are you sure?"

Galvanax's foot stomped down barely a few feet away from them, shaking the ground and creating fissures that swallowed up cars, buildings and people. Sarah felt the ground starting to slip under her feet and ran with Mick, looking for somewhere safe.

Unfortunately, since it was the center of the attack, there was nowhere safe. Galvanax was right on top of them, which meant every step he took claimed lives by the dozens. Sarah and Mick almost wound up between his toes many times until they managed to get a little further away and weren't directly under him.

"Now what?" Mick asked her, shouting because the screams of others, the emergency sirens, the sound of Galvanax stomping and buildings crashing drowned him out otherwise.

"We have to find my dad," Sarah told him. "Do you remember what he looks like?"

Mick recalled the picture Sarah showed him on her phone and nodded his head. "Any idea where he might be?"

"His friend said a restaurant."

"Which one?"

"I didn't… ask," Sarah said. She looked around, and just in time. Galvanax had taken down another building and the debris was flying everywhere. Thick, heavy pieces of concrete were raining down, and Sarah barely had time to notice they were standing right underneath one. "Shit!" she shouted and pulled Mick with her as it narrowly missed them.

Immediately, she regretted coming back. Everyone she had seen so far was dead, and it looked like no matter where they tried to run, there was danger. Being so close to Galvanax and knowing that there was trouble in seven other nearby locations meant escape was nothing more than a fantasy. This was just a sick and twisted way to prolong the inevitable death.

Just as she was about to tell Mick she wanted to head home, she noticed a man in the corner of her eye and looked over. He was stumbling and barely able to move. He was covered in dust and his clothes were torn, but he was still alive. Upon looking again, Sarah recognized her father.

"Dad!" she shouted and raced over, climbing over the fallen pieces of concrete as she did.

Mick watched her run to the familiar man with a slight grin on his face, "Well, I'll be damned…"

Sarah knew she wasn't supposed to interact with anyone, but the moment she saw her father, she couldn't help it. She needed to see him. She needed to help him. She rushed over, catching him just as he stumbled. "Dad! You're okay!"

"Sarah?" he looked to her, very concerned and very worried. "What are you doing here? Você está bem?"

"Estou bem," Sarah nodded and smiled. "E você está bem?"

"Tudo considerado," he coughed. Mick stood right behind Sarah and noticed blood was splattered on her father's clothes and in his hands. When Bill coughed, he blew out more of it.

"We have to get you out of here," Sarah insisted and let her dad lean on her as she turned around to look at Mick. "Do you have it?"

"Have it?" he asked and pat himself down. Then he looked to her with a frown. "Wait, have what?"

"The time machine, Mick. We can get out of here!"

"Oh that," Mick nodded, then slowly shook his head. "Uh, no. You had it."

"I don't have it!" Sarah shouted and her eyes widened. The moment they had arrived, they had to avoid being crushed. Mick had pulled her and they had jumped to safety. Somewhere between then and now, in their attempt to live, Sarah had accidentally dropped the time machine. "Dammit!"

"We'll retrace our steps," Mick told her calmly. "We'll pray it's not crushed. Mr. Thompson, can you walk?"

It was a moot question. Mick knew just from looking at him that Bill wouldn't survive. He was hurt and they were still in a lot of danger. Help wouldn't come soon enough. He was already coughing up blood, which meant there was internal damage.

He couldn't let Sarah know his thoughts. She wasn't ready to give up. She would never understand or forgive him if he tore her away from her father now.

Unfortunately, Bill sighed, "I-I can't. I can stand but… you have go without me."

"No," Sarah shook her head defiantly. "Dad, we came all this way to help you!"

"Get my daughter to safety," Bill said to Mick, ignoring Sarah. "I'm not going to make it."

"Don't say that!" Sarah yelled at her father, then to Mick, "I've got him, okay! Just lead the way back, Mick!"

"Sarah…"

"Pai, você vai ficar bem," she insisted. "Mick, please."

He nodded and turned around, scanning both the ground and the sky. He needed to find the time machine before he and Sarah were left stranded in the past, and he needed to watch for more falling debris and Galvanax's feet.

By now, fires were blazing. Corpses littered the ground and those that weren't quite dead were screaming out in agony, begging for help. Mick and Sarah both knew there was nothing that could be done for them, especially not without the time machine in their hands. The smell of burning flesh filled the air, bringing back from painful memories for Mick, but he pushed through.

Every time Galvanax took a step, the ground trembled, making it hard to walk. Falling debris would also shake the ground, either by stirring up what was loose under their feet, or by being heavy enough to cause a slight tremor. Mick wasn't sure how many times he stumbled.

When he looked back, Sarah was falling behind. She was strong and very stubborn. She could support her father's weight, but with the added obstacles and death threatening every step, it was starting to be too much. Mick watch her take a fall and rushed back to help both her and her father.

"I've got you," he assured them and smiled at Bill, "Oh, Mick, by the way. I'm Sarah's… uh… friend."

Bill gave a nod, and it looked like he wanted to speak, but he was struggling just to breathe. He convinced Sarah to let him rest for a minute and she and Mick set him down. Almost immediately, he started coughing again, spewing out blood. This time, there was a lot more than just a little splatter in his hand. His face was pale, he was growing weaker and Mick could tell, just by looking in his eyes, he was starting to fade.

"Sarah…"

"Mick stay with him, please," Sarah begged. "We're not far from where we started and I'm faster. I'll find it."

"Sarah…"

"Just, keep an eye on him, okay," Sarah said then looked down at her father with a smile. "I'll get you out of here, okay?"

"Stay safe," he whispered to her, taking her hand. Sarah nodded and smiled.

"I'll be right back," she told him, but her father didn't let go of her hand.

"I love you," he said. "More than anything, you know that, right?"

"Dad, don't do this," Sarah shook her head. "I've got you, okay? Just hang on. I'll get the time machine, we'll get you help and you'll be okay. I promise."

"I love you," he repeated. Sarah kissed his cheek, whispered she loved him back, then bolted off to look for the time machine. Mick glanced around to be sure they would be safe to rest for a minute. When it seemed like they were in no immediate danger, he looked down at Bill.

"You've got a wonderful daughter," he told the dying man. "She's remarkable. I'm sure you know that."

"Are you a friend?" Bill asked. Mick nodded.

"I am. I'm Mick."

"I'm not real," Bill said and Mick frowned. "Please, don't let anything happen to her for me. It's not worth it."

"You're not real?" Mick asked but Bill shook his head.

"You have to take Sarah home. You can't let anything happen to her. Promise me you'll take care of her."

"But…"

"Please," Bill begged. "Let me die. It's what's meant to be."

"I'll keep her safe," Mick promised. Bill smiled faintly and nodded his head.

"Please, take care of my daughter," Bill begged him and took Mick's hand, squeezing it tight. "She's not going to leave me. She's… she's stubborn. You need to… you need to get her out of here."

"I'll do my best…"

"You'll do it!" Bill said and it sounded like he was trying to shout. "She won't want to. She'll fight you, hard, but… you get her out of here, no matter what it takes. All I want right now is my daughter safe."

"I'll do it," Mick promised.

"You'll look after her?"

"I will," Mick nodded and suddenly the ground shook. Mick looked to Galvanax and saw his steps were getting closer. If he didn't move, he would soon find himself under the monster's foot. He reached for Bill, trying to lift him to get him away, but Bill could barely hold himself up anymore. He was nothing but dead weight. Mick knew it, and when Bill tried to push Mick away, he knew Bill knew it too.

"Take care of her," he said. "Let me go, I won't make it anyway. Look after my daughter. You promise me."

"I promise," Mick said, but he found he couldn't move.

"Go!" Bill said to him. "Go find her, please!"

"I…"

"Now!"

Mick nodded and took off running, diving just as Galvanax's foot came down, crushing everything he left behind. As Galvanax kept walking, he lifted his foot and unstable debris fell into the hole he had created, burying Sarah's father.

"Dammit," Mick muttered, but he couldn't waste time. He looked over and saw Sarah had also survived Galvanax barrelling through. She was digging through the spot where they had first arrived, looking frantically for the time machine.

Mick gulped as he removed it from his pocket. He had picked it up when he saw it on the ground as they were getting back to their feet after a dive.

Sarah's father never would have made it. Even if they could get him to the present, they were too far from a hospital and the base wasn't equipped to care for him. He wouldn't have survived the trip to the hospital and couldn't wait for an ambulance.

Mick knew he should have tried. For Sarah, he should have admitted he had the time machine and taken her father to the present. However, he thought it was best to leave him in the past. It was for the best if she knew that he had died in the attack, instead of coming so close to saving him and failing once again.

"Sarah!" he shouted as he made his way over to her, holding the time machine up. "I found it! It's here!"

She heard him and looked over with a smile. She rushed to him, stumbling many times over the debris. As she approached, she looked for her father but saw he wasn't there. "My dad…"

"Sarah, we need to go," he insisted.

"But my dad," Sarah shook her head and tried to run. Mick remembered the promise he made to her dad and so he grabbed her and held her back. He set the time machine for the present and switched it on.

Just as quickly as they had left, they were back. Mick let go of Sarah as she pulled away from him and fell to the ground.

"NO!" she screamed when she realized where they were. Mick barely had time to destroy the device before she shoved him. "What are you doing? We had him!"

"Sarah, he died," Mick explained, but she didn't want to hear it.

"We go back! Farther back! We know he was there. We know he was okay, we…"

"Sarah, we'll change everything," Mick shook his head. "It could be worse."

"NO!" she screamed and shoved him again, this time knocking him to the ground. "We have to save him! If we're there, just a little earlier…"

"We could have been killed," Mick told her. "Sarah, we barely survived once…"

"NO!"

"You went back to see what happened to him and now you know! He's dead," Mick said. "He was crushed by Galvanax and buried. By the time it all settled, he must have been under so much dirt and dust… I'm sorry."

"You did it!" Sarah screamed. "I asked you to keep an eye on him! You… you let him die!"

"I… "Mick started to say something, but he didn't know what he could say. She was exactly right. Her father would be dead regardless of Mick's actions, but the truth was that Mick had left him to die.

Sarah noticed his hesitation and it wasn't lost on her at all, "You… you…"

"Galvanax was close," Mick explained. "I tried to take your father with me but… he insisted I go without him. He insisted we get out of there."

"You let him die!" Sarah screamed. "You… you asshole!"

She hit Mick once in the chest with her fists and tried to swing again once more, but her arms were caught and held back as the other Rangers arrived. Calvin had grabbed her, while Brody, Levi and Preston stood between her and Mick.

"What's going on?" Levi asked as Brody checked to see if Mick was okay. "RedBot said to wait for you guys here, but…"

"He killed my father!" Sarah shouted and tried to pull away from Calvin, but the yellow Ranger had wrapped his arms tight around her. When she continued to pull, he lifted her, taking her feet off the ground. "He killed my dad!" she shouted.

"What?" Preston and Levi turned to look at Mick.

"I'll explain that later," Mick said. "Calvin, Hayley, take her home, please?"

"On it," Calvin nodded.
