AN: Many, many thanks to WhiteRusskie for both reviewing and for being splendid in general.
Six years later
"Emperor Gaius Julius Caesar Augustus Germanicus" Drusilla whispered softly as she stroked her brother's hair. She could hardly believe that it had finally happened, that her darling brother was finally the emperor. He was still so young; he was still her baby.
"What was it like living with Tiberius?"
The new emperor shut his eyes, attempting to forget the eventful years since he had seen his sister.
The knife was in his hand, Tiberius was on the bed. It was an impulsive plan, but so perfect. Once he was emperor, no one would punish him for it. He crouched low over his grandfather and lifted his arm. He held it in place, tried to remind himself of his parents and what Tiberius had done to them. He still couldn't do it. The knife was flung away in disgust, clattering far louder than Caligula had expected. The emperor didn't stir, however, so he picked up the small dagger and made his way out of the room. He glanced over his shoulder for a second and saw Tiberius's eyes wide open, staring with blank fear at his grandson.
The young slave girl screamed in a language he couldn't understand, though he could gather her meaning. Tears rolled down her face, cutting channels in the thick make-up. She couldn't have been more than twelve, but she was very pretty. That was Caligula's excuse to himself as he rammed into her.
"How do you think this man should be punished, Caligula?"
"I don't know, lord."
"Would you like to kill him yourself, Caligula?"
"If it would be" he searched for a word in order so as not to convey his eagerness "convenient to you, my lord."
The old man nodded, and Caligula stood in front of the condemned man. His motion was clean and swift, though the stranger's death was not. Caligula had been sure to cut into his stomach so that it would take him a good long time to die.
"Is it done, Macro?"
He bowed deeply, a hint of apprehension on his features.
"It is done. You are now the Emperor, my lord."
"It was horrible."
"You're safe now, darling" she whispered, her eyes full of concern.
Wishing to terminate any further discussion, Caligula picked up the tiger cub he had brought Drusilla and placed it on her chest. She scratched behind its ears and let it bat at her hand.
"Shall we get married before or after the ceremony?"
Drusilla gave a small start, annoying the striped bundle of fur.
"Gaius, I-"
"If we do it before, we'll be officially crowned together and everyone will be used to the idea". He reached out to stroke the re-settled tiger. "But if we do it afterwards, we shall give the public a completely new reason to celebrate, and have two official ceremonies instead of one."
"Caligula, you know we can't get married. We're not Egyptian."
"I am the Emperor" he said simply and with a dangerous smirk. "I can do whatever I want, whenever I want, to whomever I want."
"Just don't start with me" she retorted nervously as he ran his hand up and down his arm. "We'll discuss it later, Gaius."
"Should I kill Crassus, or just force him to divorce you?"
"Oh, please let us be divorced, no matter what."
He shrugged. "I shall think about it"
He sat up next to her and hugged his knees to his chest. He had grown more muscular since she had last seen him, and his face looked leaner and far less adorable than it used to. She wondered what he had gone through while he was in Capri and if he would ever tell her.
She rubbed his shoulders and gently tugged at him until he eventually lay down next to her again and started playing with her hair.
"If we were married, you could have absolutely everything you want.
"Go to bed, Gaius. And you too, my little darling" she crooned, kissing the top of the cub's head.
She saw another shadow of fear cross her brother's face when he thought she wasn't looking.
"I love you, Gaius. And after I've introduced you to all the suitable women I know of, if you absolutely despise all of them, I shall reconsider marrying you."
"Drusilla, I will never love anything as much as I love you."
She knew he was right, and that their being married would be wonderful. She'd have the respect she deserved and there could even be games, feasts, and anything else she wanted in her honor. Regardless of everything else, she and her brother could spend all their time together. Not that either could be expected to remain faithful, of course. Drusilla knew that both of them needed many different types of experiences to remain satisfied. If she were Caligula's queen, she would make sure that only the wisest men were chosen to remain senators, and they would only do what she and her brother told them to. Dissention would be dealt with harshly, she decided. After all, she and her brother were Gods; normal laws didn't apply to them. If only the people could understand. Drusilla knew that she and her brother could rule without a senate, but if the people thought they were aberrations against nature, their reign couldn't last.
"Gaius, there were times I thought I'd die without you"
"Well, of course there were"
Insolent little fool she thought, before drifting off to sleep.
