"I can't believe you've kept it all these years!"

The Doctor's face was lit up like a million joyful children on a million Christmas mornings. Sitting in the UNIT garage, hidden under an old tarp for decades, was an automobile that shined in flawless canary yellow, Bessie. The old Edwardian roadster had not been used since the Doctor left UNIT and, despite some wear from the passage of time, looked like the terror of the motorways that the Doctor remembered it being.

Kate was firing up the engines of a nearby jeep which, compared to Bessie, was quite drab.

"Oi, you're not coming in Bessie?"

"Not enough room, Doctor. Plus, you may need cover."

Samuel hopped in to the passenger side of the jeep.

"And I'd rather ride in something that looks like it'll actually drive," he said, "no offense meant, Doc."

Harriet was helping the Zygon into Bessie's smooth leather backseat, or at least, the form the Zygon was now in. To the unknowing eye, it looked as though Harriet was helping a tall, blonde haired woman in military dress into the car.

"Sorry about hitting ya before," Harriet said, "I got a bit anxious."

"No need to apologize," the Zygon's voice was now raspy, but warm like honey, "I didn't really give you much of a choice. Thank you…thank you for all of this."

The Doctor slid the key into the ignition and the roar of Bessie's engine reminded him even more of why he loved this old jalopy so much.

"I can't believe this thing still runs!" Harriet said.

"Never doubt old things," the Doctor said, "they may not always work the way they used to, but you can't learn anything new without them."

The Doctor pulled out his sonic screwdriver and opened the garage door with a quick point and press of the alien device.

The pair of vehicles drove out into the night and away from UNIT headquarters. But unknown to the wayward quartet and their extraterrestrial fugitive, another door in UNIT headquarters opened as they made their escape. When this door opened, a gargantuan tank treaded over the ground and began the pursuit of its quarry.

UNIT's dedication to keeping their operations secret meant that their headquarters was located just outside a small village along the coastline in the country. Few people knew it was there, and most who knew about it, didn't really care much as to what was going on within its walls. The summer air was some of the cleanest air that Harriet had ever breathed in her life. She turned back to check on the Zygon. It was staring up at the array of stars that could be seen as clearly as anything. The pleasant blonde haired woman glowed and turned back into a large starfish.

"Doctor," Harriet said, "you've been doin' this kinda thing for awhile, yeah?"

"Longer than you'd believe," the Doctor said. Harriet could tell by the weight in his voice that he was telling the truth.

"I…well, when I was a kid," Harriet's face went flush with embarrassment as she told her tale, "I used to hear stories about my great, great grandfather. They called him 'Mad Jamie' and he was this daffy old man who told stories about travelling to other planets and fighting monsters…no one ever believed him though. He lived his whole life in the highlands and then in his old age he starts raving. And most of the stories he couldn't remember all the way through. Like someone had erased the beginnings or the middles from his mind."

"Are you asking me if he was right?" the Doctor asked.

"No, not exactly. He always mentioned a man. A funny man in a bowtie. The Doctor. He…you can't be…"

The Doctor smiled.

"Jamie McCrimmon," the Doctor voice caught in his throat, "Harriet, did you believe the stories that 'Mad Jamie' told?"

"Yes," she said, "especially after today, yes."

"Then that is all that matters."

The choir of chirping crickets was now accompanied by a low clanking sound, gradually moving closer and closer to the two vehicles. The Doctor looked over at Kate, driving alongside him. Her face looked grim. She reached for the walkie talkie sitting on the dashboard.

"Keep driving, Doctor. We're going to fall back and see what that is," Kate's static-filled voice said through Harriet's walkie talkie. But the answer came sooner than they were expecting. In the darkness, a single spotlight illuminated Kate and Samuel's face and then swooped over to Bessie and her passengers. The spotlight was attached to the top of a creeping tank that stalked closer and closer like a predatory cat, ready to pounce. Peeking out of the top of the tank was Colonel Albright.

"Doctor!" the Colonel's voice echoed and squawked through a megaphone, "this is your final warning! If you do not return the prisoner, we will open fire!"

"Do you have anything to slow it down?" Harriet shouted.

"I've got an anti-theft force field, a remote control, and an inertia hyperdrive, but that's a bloody tank!"

A deafening blast interrupted any plans the Doctor had at that moment. Both drivers twisted their steering wheels to avoid the explosion that fell between them.

"Director Stewart," Samuel said, "permission to do something rather crazy and stupid?"

"Those are the only options we seem to have left!" Kate said.

"Get us next to the tank!"

The Doctor watched as Kate's jeep made a sharp turn back in the direction of the tank.

"We're going to have to be a distraction!" he said to his terrified passengers, "I'm brilliant at distractions, though! Brilliant!"

Bessie kicked up dirt as she skidded along the dirt road and sped back towards the metallic monstrosity. The tank's gun couldn't decide who to fire on first; it creaked back and forth, before finally choosing Bessie as its target.

"Okay everyone," the Doctor said, pointing his sonic screwdriver at one of the devices attached to the steering wheel, "we're going to try something I've never actually done before, but, in theory, it should work!"

"What theory?!" the Zygon shouted.

"The one I just came up with in my head, now hold on!"

The Doctor drove straight towards the tank's gun. Another shot fired into the summer night with the same intensity as the first. The shell hurtled towards Bessie. The Doctor, Harriet, and the Zygon shouted as they saw death flying towards them. Just when the impact seemed inevitable, the shell flew right over the car as if an invisible force suddenly scooped it up and threw it miles away.

"Ha!" the Doctor shouted.

"How did-?! That was-! WE'RE ALIVE!" Harriet couldn't catch her breath. She was sure her life was going to end next to a kook in a bowtie and a big starfish from space.

"Magnetic force field anti-theft device," the Doctor explained, "normally, it magnetizes any unwarranted users and makes them stick to the car, I simply reversed the polarity of the magnet to push things away rather than pulling them close."

"That's it?" Harriet said, "Just reverse the polarity?"

"It's always surprisingly effective," the Doctor said, "and look what our friend Samuel is up to!"

During the commotion, Samuel managed to climb on top of the tank. He was trying to pry open the entrance like it was a deadly can of soup. The opening suddenly flew open and struck Samuel in the chin, knocking him backwards. One of Albright's soldiers emerged and tackled Samuel onto the surface of the tank, next to the base of the gun.

"Doctor, we need to-"

"Way ahead of you!" the Doctor slammed his foot on the gas pedal to reach the side of the tank. In the back of the car, the Zygon coughed up a black goo.

"Doctor," it said weakly, "I'm-" but it couldn't finish, the pain of simply speaking was too great.

"Doctor, as soon as I get up there, you need to go," Harriet said.

"No!" the Doctor said with fury, "I can't leave you, I refuse-"

"Director Stewart can watch out for us, but if you don't get him to safety, then all of this woulda been for nothin'."

"Fine! Fine! You McCrimmons, always so damn stubborn!"

Harriet thought about what that meant for a moment. She thought about all those amazing stories her parents told her, usually with hint of irony in their voice. They never believed in those fictions that had made their family a mockery for years, but Harriet knew, somewhere in her mind, that the man in the blue box had to be real. Now she knew for sure.

Samuel had managed to get the upper hand against his attacker, but he was still in no shape to continue the fight on his own. A hard punch to the eye when he was pinned was making it nearly impossible to see. The two men grappled in a stalemate. Neither seemed willing or able to give an inch to his opponent. Samuel felt the adrenaline start to fade. His body felt weak and just when he thought he had lost, a fist smashed into the jaw of his attacker, knocking him clear off the tank.

"Hey, Sammy," Harriet said, "oi, that's a nasty looking bruise you're gonna have there."

"McCrimmon, I owe you a drink after this," Samuel said.

"Don't be daft, Sammy," she said, "you owe me at least three."

They watched as Bessie sped off into the night with flames bursting from its exhaust pipe. Another two soldiers popped out from the tank. The first immediately took a swing at Samuel. He managed to duck and delivered two hard punches to the soldier's stomach in return. The second didn't even get a chance to attack Harriet before she went charging into a diving tackle that sent both of them flying off of the tank. The two bodies hit the ground hard while the tank continued its war path, unfazed.

"Oh, I gotta think before I start tackling," Harriet thought to herself. The soldier landed a few inches away, unconscious. She slowly got to her feet as Kate stopped her vehicle right in front of her.

"McCrimmon," the director said, "are you okay?"

"Aye, sure," Harriet tried to lift her arm to wave off Kate's concern, but a flash of pain kept her from lifting it more than a few inches, "actually, my arm is definitely broken."

Kate climbed out of the jeep and began to untie Harriet's boot.

"I'm going to need both of your boots," the director said to a visibly confused Harriet, "and a grenade."

It seemed as though Colonel Albright and his men were determined to take their frustration in losing the Doctor out on Samuel. The tank charged onward with some glimmer of hope in apprehending the Zygon again, while Samuel continued to trade blows with one of the comically large soldiers under Albright's command. Samuel hadn't felt this exhausted in years. Not since the match before his career ending injury. The score was tied. Samuel had been playing for almost the entire game. His energy seemed to feed off of the roaring crowd that packed the stadium. And when he made that final kick to win it for his team, he had a feeling in himself like nothing in his life. Until tonight. Maybe it was all the blows to the head, but he could have sworn he heard all of those screaming fans again: cheering on his team, cheering for him. This could be the end, but at least he knew he would have won it all for his friends.

Samuel was so punch drunk he almost didn't believe it when he saw director Stewart leaping onto the tank from the jeep driven by Harriet. Real or not, it was all the motivation he needed to deliver one strong uppercut to the muscular menace that had been plaguing him.

"Samuel, get clear!"

"Yes, mum!"

Samuel staggered to the edge of the tank and didn't jump so much as fall into the back of the jeep.

Kate, who had replaced her business casual heels for UNIT regulation combat boots, grabbed the grenade as tightly as she could. She took a deep breath and ignored all of the thoughts in her head telling her this was the worst idea she's ever had. She began to run up the gun of the tank, one foot at a time, like the balance beam in her childhood schoolyard. The gun flew up and down to shake her off like an arm does to an irritating fly. Her balance gone, Kate began to fall, but managed to catch the gun with both hands. The price for her safety was the loss of the grenade, which fell under the tank's unstoppable path. Kate swung up and managed to wrap her legs around the slowly cooling gun. Her gloves and pants barely managed to keep her flesh from burning. She shimmed slowly up the gun and tried to think of a way to fall without being crushed under the unforgiving treads of the tank. Before she could risk dropping down, Harriet swopped under the gun. Samuel, still sitting in the back of the jeep, had his hand raised with a grenade clutched in his fingers. Kate reached down and grabbed the explosive as quickly as she could. Without even needing to be told, Harriet drove as far away as she could. Kate managed to shimmy up to the top of the gun. She ripped out the pin with her teeth and held it for a few seconds. The tank came to a sudden stop as Kate slipped the grenade straight down its open barrel.

A few soldiers and Colonel Albright rushed to escape the newly made time bomb. The explosion knocked Kate off of her feet and into the dewy ground. Her body was relieved to feel the cool grass after the flames nearly lit her on fire. She stared up at the stars and could only think about what her dad would say at this moment.

"Damn good work, Kate," she said, emulating her father voice.

Miles and miles away, the Doctor stood with the seemingly endless sea before him. His companion was completely quiet. It wasn't quite sure what to think. Any traveler who had been on a journey as long as the one it had taken would feel the same trepidations knowing that it had finally come to a close.

"This is the end," it whispered with its weakened voice.

"No, don't think of it that way," the Doctor said, "it's the beginning of something no one has ever seen before."

The Zygon lifted its head high. Step by step the ocean reached higher on its body until it was out of sight completely, swallowed by the dark sea. The Doctor stood on that shore for awhile, listening to the gentle waves and contemplating the reflection of the moon against the water.

"So, you can just fire him, just like that?" Harriet asked. Her arm had been put into a makeshift tourniquet made from one of Samuel's pant legs.

"Well, I'd say trying to kill two of your subordinates is sufficient enough cause for a sacking, wouldn't you?" Kate replied. "Besides, I'd say I already have two very good candidates to become the new Co- Assistant Heads of Military Affairs."

"I'd be more excited if we hadn't run out of gas," Samuel said. The trio was stuck walking back to UNIT headquarters, though for all the energy they had, it was more like they were shambling back. Luckily, the sound of a roaring engine brought some relief.

"You all look like you had quite a time without me, eh?" the Doctor pulled over and let his weary comrades into his yellow beauty. "Where's Alby gotten off to?"

"He is no doubt walking to the nearest bus stop," Kate put her head back and shut her eyes, "no doubt I'll get a bunch of nasty calls tomorrow, but I'll get them to see my side of things."

In the back of the car, Samuel rested his head against Harriet's shoulder and immediately dozed off. With the wind blowing through their hair, the Doctor drove back to UNIT.

"I meant to ask, Doctor," Kate said, "how have Amy and Rory been since I last saw them."

"Oh, they're wonderful, those two. I'll be seeing them tomorrow, actually. We've got a little day trip planned. New York City. It should be fun."

Kate eventually joined Harriet and Samuel and slipped off into a deep sleep as well. The Doctor sat in the comfortable silence and smiled.

"Good memories," the Time Lord said, "always need a few good memories."
