This is me whenever I write a paper for school. If only I had Tadashi to help me look at things with a new perspective, maybe I'd be getting A's instead of B's. (Update: I actually just found out that I am getting A's in my classes. BUT I STILL WISH I HAD TADASHI TO HELP ME.)
I think this is more than just a parallel. Here in these scenes, Hiro is using the same words while he's a superhero, that tadashi said to him. I think this means that Hiro thought those were things a good superhero would say to others. Which means that Hiro saw Tadashi as a true hero. <<<FEELS.
