Thor happily sat next to his brother at the dinner table and threw a hearty smile at his mother and father as he began munching down his food.
"My boys, how was your day?"
"I have a new subject. Groot." Thor said happily. "The language is so funny." Loki huffed at that.
"It's primitive. There's no depth, it has only three words!" He informed his brother more or less gently. "I see why you choose it." He added as an afterthought and resumed eating his dinner.
"Hey!" Thor protested. "It's extremely difficult. It's a very emotional language."
"Uh huh." His brother muttered unimpressed. "You could have chosen literally any language. Why that one? I'll bet you're never meeting a groot in your life."
"And what if I will? When I'm older I will visit all the realms and the whole universe. I will meet plenty of groots!" Thor protested with a triumphant grin.
"It's Flora Colossi, actually." Loki corrected him with a smirk as if he hadn't just said the same thing but Thor wouldn't let his brother ruin his mood.
"Whatever, I'm seeing many of them and when I have made friends I will bring them here and who isn't able to talk with them then? Right, it's you!" Thor said finally and stuck his tongue out at his brother.
Loki just waved him off, showing he was finished with their conversation but Thor still had too much energy and needed to argue with someone.
"What languages are you learning then?" He asked mockingly. Loki faced him with a neutral expression.
"I have to concentrate on studying the arts of seidr. But if you must know, I am taking lessons in midgardian languages." Thor crinkled his face at that.
"Midgard? I thought that realm was beneath you."
"It is. But they do have some beautiful languages. And quite a few of them as well. For such a primitive race they do like to make up words for everything."
"It's like the Flora Colossi are a highly intelligent race and don't need so many words to express themselves." Thor chirped up, satisfied with his observations.
"That's not what I said."
"But it's true!" Thor grinned at his brother. It wasn't often that he won their verbal matches.
Loki just huffed.
"We'll see that when you will bring your….friend."
"Yes, yes we do!" Happy that his little brother finally relented, he returned to his meal but he couldn't refrain from shooting smirks at his brother every once in a while.
A few hundred years later when Thor did in fact bring a young Groot into the halls of asgard he hadn't thought he would have to look into Loki's pleading eyes at the end of the day asking if they could keep him. It was hard to say no but then he remembered the feisty rabbit and his threats If Thor wouldn't bring his Groot back.
