The Doctor, Time Lord and... babysitter?

The Crystal Empire:

All was silent except for the cold wind rushing through the frozen wasteland. Nothing made a sound, not even a animal. After all, how could they when there was no animals around to make them? Then, there was a sound breaking the silence.

VWOOP! VWOOP! VWOOP

"Weeellll, that was rather enlightening wasn't it? Okay, so as it turns out Sea Ponies do not like it when you say you've eaten fish at least once. Huh, wonder why?" The Doctor muttered as wind whipped his grey fur and blew his mane in front of his face. He was dressed in what you would almost certainly not wear in cold weather like this. Said attire consisted of a gaudy flower print shirt not out of place from those in Hawaii and sunglasses along with a fez. "Mental note. Spears are not cool!"

Now, you may be wondering what the Time Lord was doing here. King Sombra returning? Lizard people coming up from under the earth? Daleks attempting to destroy the Crystal Heart? Well, you'd be wrong on all counts. It was none of those things actually. Quite recently, he'd heard his companion Shining Armor along with that wife of his had become parents. He wanted to congratulate the two. Mind you, he wasn't sure if he landed at the right time and it was entirely possible he'd landed too early and would just end up creating some awkward moment like when he burst out at the wrong cake at a bachelor party when he was looking for Shining to tell him the world was about to end via Cyberpony/Weeping Angel team-up. Long story.

"Well, here goes nothing..." He said, as he fixed his tie and fussed with his hair. "Geronimo."

"HEEELLLLLOOOO! Anypony home?" The Doctor called as he opened the two large doors that led to the Crystal Palace's throne room. "Huh, I was expecting the guards by now to have been pointing sharp and pointy objects at me. Maybe I should have sent a memo... Nah, surprise visits are cool. Fact."

Then he got his wish as guards pointed said aforementioned sharp objects at him.

"...Of course, there  are someponies who don't share this view but oh heck what do they know huh?" He asked.

"Who are you?" One guard asked. The Doctor grinned.

"Glad you asked my good sir. I'm the Doctor, also known as the Oncoming Storm, the Predator and Your Worst Nightmare... among others but we shall not go into those eh?" He replied with a manic grin as usual before bowing. The guards weren't very impressed. The captain gestured to two of his men.

"Take him to the dungeons. We'll let the Prince and Princess decide what to do with him there." He said, and two guards grabbed the Time Lord much to his great dislike.

"Now now, we can talk about this. No need to resort to-Hey, watch it mate! You could hurt somepony with that, like me!" He protested after being poked with a spear to make him trot forwards.

"Alright, what's going on here?" Shining Armor asked as he trotted into the room alongside his wife. "I heard shouti-Doctor, what did you do? Actually, for that matter why are you here?"

"Well, I was going to congratulate you for the baby but these guys thought I was some sort of villain! Mistaken for a villain incidents are not cool!" He protested and Shining sighed before facehoofing. "Release him. He's a old family friend."

"First off, I want to ask are there any threats to the Empire I should know about?" Cadence asked the Doctor. "No offence, but I have heard where you go trouble follows."

The Doctor looked somewhat offended.

"Oh ye of little faith... I can go places without somepony trying to kill me." He said dryly.

"Well you do have a track record." Cadence replied as Flurry cooed.

"She wants milk." The Doctor said simply and Flurry's parents looked at him in shock.

"I speak Baby." He answered, as if that said it all. Shining sighed and rubbed his temples before muttering "Of course you do..."

Flurry cooed once more and tried to reach for the Doctor's tie and pull it off. She eventually decided to just suckle on it. He groaned while Cadence giggled and Shining laughed his head off at the Time Lord's obvious discomfort. "Yeah yeah, laugh it up." He muttered.

"Looks like she likes you Doctor." Shining snorted as Flurry cooed again. The Doctor looked down at her before saying "No, I'm not your mommy, she is. No, she's not just big milk thing and no you can't bump her and your dad off and rule the Empire by yourself." He whispered before looking at Shining.

"Looks like your kid wants to take the Kylo Ren route and take over. Watch yourself."

Shining and Cadence looked at him like he was crazy. Well, crazier then normal anyway. Now the Doctor was the one rubbing his temples.

"...Never mind." He muttered as a guard rushed in. "My Lieges, Princesses Celestia and Luna need you in Canterlot! It's urgent."

Shining swore under his breath. He knew he'd have to leave Flurry behind and the Royal Babysitter was out sick with the Feather Flu. Suddenly he got a crazy idea and looked at the Doctor seriously who along with Cadence grew rather nervous.

"Uh Shiny, what are you doing?" The Princess of Love asked nervously.

"Doctor... This may be the most difficult task I have ever asked of you. Will you look after my child?" Shining said seriously and his tone indicted he wasn't joking although the Doctor wished he was as Flurry continued suckling. He didn't know how to take care of a baby, and one who was a magical princess who nearly destroyed the Empire at that. But then he looked at Shining's pleading face and Flurry's admittly adorable features.

"Well... She is kinda cute... Oh what the heck? I'll do it!"

Yeah, this wasn't going to be too hard. He'd faced down Daleks, Cyberponies, The Master and Weeping Angels among many other things over the years. He could do this! After all, how hard could it be?
