Akito’s left hand starts feeling Killua’s chest, he had already managed to get the rhythm of his heart beat, but now, was trying to figure out what was the energy passing inside Killua.
“It… sounds like… could it be electricity?” he concludes to himself “But… how could he…”
His right hand reaches the other guy wrists, feeling all the scars, he could distinguish the time line in them now, the way they had healed, and the way they had appeared on Killua’s body.
He suddenly stops, feeling a new scar.
“This one… is a burned…”
He remembers Killua saying about his family torturing him, but his mind was having a hard time to accept that reality.
“I… it cannot be… some of this scars are… from his early childhood.”
An electrical discharge sound arrives in his ears.
“Could… it be… that he… was tortured… to this point… by his own family.
No… Thus this mean that… this guy…”
His focus breaks, he falls backwards, not being able to stand hearing more.
“He… suffered all that… from his family… and… all alone…”
He starts crying, in a few seconds sobbing.
