Here is a very short, but very cute thought that popped into my head.
Tsuna stared at the playpen in worry and confusion. Playing inside the plastic 'cage' were Mukuro and Kyoya but they were only two years old. Mukuro didn't have the red-eye, and neither could speak. Tsuna turned to the four scientists looking for an explanation.
Verde nonchalantly shrugged. "I was testing an experiment and those two started to fight and broke my machine and that was the result."
Giannini gulped. "They also destroyed half the lab before this happened."
Tsuna looked to Spanner and Shoichi gaining nods of agreement. The brunet sighed running a hand through his hair. "Great... I needed them for a mission... Verde, can you reverse this?"
Verde nodded. "I can but it'll take a month."
"Very well, do hurry," Tsuna said, before moving over to the pen hearing one of the two crying. Mukuro was holding the top of his head bawling while Kyoya held the toy car to his chest glaring. Tsuna gently picked up Mukuro, which promptly made the baby illusionist hide his face in Tsuna's shoulder muffling his sobs. Tsuna looked at Kyoya who had gone back to playing with his toy car like nothing had happened.
"Kyoya... You don't hit." Tsuna scolded gently, trying to soothe the bawling baby illusionist. Kyoya ignored Tsuna kicking the blocks Mukuro had been playing with away. Tsuna sighed bouncing and rocking Mukuro, the cries slowly dying down to hiccups. Kyoya continued to ignore the brunets efforts to scold him for hitting Mukuro. Tsuna soon gave up as Mukuro fell asleep soothed by the sky flames Tsuna was unconsciously giving off. Tsuna looked at Mukuro still hearing the hiccups. What he saw was the baby illusionist asleep with his fist in his mouth drooling on Tsuna's vest and button-down. He carefully took a picture and moved to sit down to watch Kyoya play with the toy car.
