This one takes place sometime after Tadashi's death. Really any time. Tadashi visits as a ghost, feeling Hiro's desperation.
Disclaimer: I do not own Big Hero 6. The story title also comes from Travelling by Ambulance by Monarchy.
Burnt Fingers
VII. I'm Here
Tadashi sometimes found himself awakening in his bedroom, his eyes immediately falling on the sleeping Hiro. His sleep was restless; he was having another nightmare, full of flames and shouting.
He was pulled here for Hiro.
Tadashi wanted nothing more than to wake Hiro, tell him it was all going to be okay. But he couldn't do that anymore.
Instead, Tadashi placed a hand on Hiro's head, breaking the nightmares.
"I'm here, Hiro."
"…'dashi," Hiro muttered in his sleep. "…miss you…"
He was always gone before Hiro woke up, but Hiro remembered his voice breaking through the flames without fail.
Hope you enjoy.
