[The physical withdraw is more than enough to turn that concern on Tadashi's face into real worry. What could Hiro possibly have done to make him pull away like that? The younger Hamada hadn't looked this uncomfortable when he'd gotten the both of them tossed in jail.

Tadashi's face shifts further as Hiro talks, worry replaced with brief confusion and disbelief, and then dismay.

Hearing about Hiro's original changes to Baymax had been bewildering at first. He'd seen pictures and video of his healthcare companion decked out in armor and flying through the skies as if he'd always been meant to do so. It wasn't anything Tadashi had ever intended for Baymax... but he couldn't help but be amazed. Hiro had done some incredible things in Tadashi's absence, and if they were still helping people, well how could he ever be upset by that? More than once already he'd wondered if Baymax was really his project anymore, but hearing this... His creation turned killing machine and his brother nearly turned murderer, and all for him...

Tadashi's silent for a bit. Not too long, but probably long enough to make Hiro even more uncomfortable than he already was. His voice obviously carries his disappointment when he finally responds, eyebrows furrowed and expression troubled.]

... Baymax can't be a weapon. Ever. And neither can you, no matter how much you hurt. You can't let anger change you.

Do you understand?
