Austria and Hungary stood outside Prussia's front door, both hesitating to knock.

"You knock..." Hungary whispered, nudging Austria's arm. "He likes you more."

"No, you do it."

"No, you. He has a grudge against me. I've already told you."

"Fine." Austria sighed, bringing his hand up to the door and knocking.

"Greetings, suckers!" Prussia answered, swinging the door open and smirking at his two visitors.

"Glad to see you haven't changed." Austria remarked, as he and Hungary marched inside and entered the living room. There, a young adolescent sat all by himself reading a book, not noticing the extra people in the room. As Austria and Hungary gazed at him, they noticed the uncanny resemblance he had to Holy Roman Empire.

"Stand up and greet our guests!" Prussia snapped at the boy, and he immediately sprung to his feet.

"Hello, it is a pleasure to meet you two." The boy said with little emotion on his face, as if the line had been rehearsed.

"This is Germany, my little brother." Prussia said proudly, ruffling the boy's hair and grinning.

"My name is Austria."

"And I'm Hungary."

"We're married." Austria explained. Hungary grimaced.

"Well, let's get down to business!" Prussia urged, growing impatient. "The sooner we make this alliance, the better!"

"You're really afraid of Russia, aren't you?" Hungary asked.

"Am not! We're doing this so that I can protect you both if he invades!"

"Liar..." She muttered.

The three older nations sat down at the table to sign the treaty, only for Prussia to notice the empty fourth chair. Turning to look at Germany, he called the young country over to join them.

"Remember, you're a fully fledged nation. That means you should also have a part in these things."

Germany, Austria and Hungary introduce themselves to each other.

On October 7 1879, Germany and Austria-Hungary signed the Dual Alliance Treaty, pledging to aid one another in the case of an invasion by Russia. Since Otto von Bismarck was Prussian by birth, I guess it would make sense for Prussia to still be the dominant one when it came to foreign relations.
