Chapter Text
Hiro remembered when it started happening. It hadn't been that long after the fire at the Student Showcase, and Professor Callahan's failed attempted at stealing him microbots. It started before Tadashi was released from the hospital with only a few cuts and bruises.
Hiro remembered that moment very clearly. Tadashi was trying to run into the burning building to save the Professor, and Hiro was holding him back.
"Tadashi no!" Hiro pleaded.
"Someone has to help!" Tadashi said.
"But you'll di-"
Hiro was cut off as the building exploded. Tadashi shielded the smaller Hamada's body with his own and threw them both onto the ground.
After the fire was put out the firefighters had found out that Callahan had started the fire and failed to surround himself with the microbots before the explosion. Tadashi was put in the hospital for a week for observation.
On one of those nights Hiro woke up with a cold and sticky feeling on his legs. He had wet the bed. The young Hamada was mortified and rushed around changing the sheets.
This happened every night, even after Tadashi came home. Hiro had to be cautious as not to alert his brother of his accidents. It would be too embarrassing.
