"Why is it easier to bust up triads then getting through one conversation with my girlfriend?" -Mako

"Uh..." Korra began, stealing another glance at The Doctor, flashing a 'help me' pout.

The Doctor rolled his eyes. "Oh alright..." He came around from his spot behind the console. "Hello, you must be Tenzin." He said casually, outstretching his hand.

"And who might you be?" Tenzin asked coolly, ignoring The Doctor's friendly greeting.

"Oh boy..." Korra groaned. "Tenzin, this is The Doctor. He's an old friend of mine."

"How old?" Tenzin asked, crossing his arms.

"From when I was Wan." Korra mumbled.

The Doctor cleared his throat, putting his hand down. "Well..." He looked over the rest of Korra's friends.

Mako was glaring at him, and Asami and Bolin just didn't know what to make of him.

"Is he your new boyfriend?" Bolin asked the Avatar, curious.

Korra's cheeks flared as her jaw dropped. "What? No! He's older than me! I'm only 17!"

Tenzin huffed. "That doesn't explain where you have been! You better have a good explanation, or you're going to be in trouble." He warned.

"You're not my dad." Korra growled.

"Anyway..." The Doctor cut in before it got ugly. "Korra, may I talk to you... in private?" He didn't wait for her answer, and he dragged her inside, locking the doors behind them.

"What's gotten into you?" Korra asked, amused. "Not a very good impression, kidnapping the Avatar right in front of them." She teased.

The Doctor laughed. "Well, there's no possible way to explain what you've just went through, so I decided to take the easy way out. So! First adventure, where shall we go?"

Korra tapped her chin, faking thought. "Somewhere fun." She said with a grin, sitting down on the jump seat.

The Doctor flashed her his 100-gigawatt grin. "You wish is my command!" He announced with a laugh, pulling a lever and sending the TARDIS into a rocky flight.

After all of the shaking and holding on for dear life was over, The Doctor outstretched his hand to the young Avatar.

"Where are we?" She asked, barely containing her excitement.

"We've landed on the Planet of the Talking Horses! Never really needed a name, only the horses are allowed to live here. This planet is protected from poachers and hunters, only a select few are allowed to land here. But since we didn't have to trip any alarms, we can do our own tour!" He told her.

Korra's eyes sparkled with glee as she pulled the doors open, and her eyes were met with a lush, green and beautiful forest setting. The sun sparkled through the vast amount of leaves, casting a dancing pattern on the grassy ground. Korra's breath was taken away to say the least.

"Wow..." Was all she could manage as she stepped out onto the new world.

"Also, on a side note, Naga has to stay here. The horses are very uncomfortable even with us here, but another animal would be chaos." The Doctor added, rubbing a hand through his hair sheepishly.

Korra rolled her eyes. "Stay Naga." She told her pet who was currently trying to get through the doors. Naga let out a whine, but backed up and obeyed her owner. "So, where are all these talking horses I've been told about?"

The Doctor looked around, suddenly very confused. "I'm not sure! They should be roaming around wild, but there seems to be none in the area!" He pulled out his Sonic Screwdriver and quickly scanned around. "There's no life forms besides us around this area!"

Korra gulped. "I suddenly have a bad feeling that we've stumbled in on a bad time..."

The Doctor grimaced. "You may be right. I wish the TARDIS would've at least brought us somewhere nice for your first ride through space and time, but I see she had other plans." He glared at the time machine, earning a loud hum from the blue box.

Korra giggled under her breath. The Doctor looked at her.

"What? What's so funny?" He asked.

"Oh, nothing. You act like she's your mother sometimes." Korra smirked.

The Doctor sighed. "Sometimes I think she is. But never mind that, Avatar, we're going to find out where all the talking horses are. Maybe our first adventure won't be so safe, but you'll fight along side me like in your dreams." He smiled.

"Hopefully we don't have to fight..." Korra mumbled.

"Yes, that is a good hope. Let's hope that." The Doctor agreed.

Korra rolled her eyes at him, he could be so daft sometimes. And yet, when she looked at him, a feeling she could not identify burned in her heart.

The Doctor watched Korra as she picked a direction and promptly walked off. One day, there will be a companion that doesn't wander off. One day. But he couldn't help but smile. It was so much like Korra to just take control. He rather liked some of her traits.

Korra made sure to take in every detail of the setting she currently walked in. She knew they were in possible danger right then, but it was just so cool! Standing on the ground of another planet!

"This planet..." Korra piped up, "does not seem to be much of a change from Earth's biomes."

The Doctor shrugged. "Well you said something fun. What's more fun than talking horses! Well, maybe Daxil, the planet of water slides..." He became lost in his own thoughts.

Korra chuckled quietly. Classic Doctor. Though her connection the Wan and the rest of the Avatars, she still had some vague memories of The Doctor back with Wan.

The Doctor grabbed her hand suddenly, stopping her. "Wait, Korra. Something's horribly wrong."

Korra turned to face him, and his expression was deadly serious. Korra's good mood disappeared. "Danger?"

"Quite possibly. I'm registering three life forms heading towards us. It looks like two of them are chasing the third." He said.

"Poachers? Hunters?" Korra asked.

The Doctor shook his head. "No. These readings are not humanoid. All three are either horses or...something else." He replied, his face now grim.

Korra felt her self-defense gene kick in, and she felt a rather odd breeze suddenly blow past.

"Korra... Don't go over the top." The Doctor warned, "that means no Avatar State here. Not until we know what we're up against."

Korra's heart pounded in her chest as she heard approaching hooves.

"Get ready..." The Doctor said, squeezing her hand a bit. "DUCK!"

Korra and The Doctor dropped to the ground as a chestnut horse came leaping over a tree root, and them. The horse still spotted them.

"Run! If you want to still live, you've got to run!" She said before bolting off in the other direction.

"Run from what?" The Doctor asked, but the horse was already long gone.

Korra then heard a voice. Two voices, actually, And she suddenly froze up in fear as her brain registered the sound. She looked at The Doctor with fear in her eyes and saw a mirror image.

"No..." He mumbled. The voices grew louder.

"But it can't be!" Korra cried, tone edged with panic.

"But it is..." The Doctor breathed. We're in big trouble now..."

"EXTERMINATE! EXTERMINATE!"
