I heard a loud crash-" she stopped as she spotted allen lying flat on the floor,and reever muffling some stuff she could'nt understand. "NII-SAN!" lenalee called,knowing that her brother would be responsible for the potions that had just smashed,komuistepped inside the room to almost be bowled over by reever, "MHMMMF FHMMM MHHHMMMM" It sounded like reever was trying to say something, "oh no,i woundered where those potions had gone to,im sorry reveer but it seems that you have lost your tongue,but don't worry it wears off in a few days" komui said cheerfully as though nothing had happened, "but nii-san what about allen-kun!" lenalee said after spotting a small child with reddish sought of hair going down to the kids shoulders,with over-sized clothing on.
"opps,it seems allen has gotten the de-age by 10 years potion,and he should only have his memories up untill he was 5" komui stated, "I was beginning to work on an antidote for that","but this means allen-kun is a 5 year old know?!" lenalee spoke, "what do we do know?"
