Ryuutaro would've at least raised an eyebrow at that scene, if he hadn't been so worried and out of his mind right now. His thoughts were fluctuating in odd manners and he really couldn't care less about beaten doctors right now.
So he paid Shamal absolutely no mind and just kind of fell to his knees next to Hayato's bed.

"I'm so glad..."
And he was. He wanted to take Hayato's hand, anything, but as he reached out he noticed that there was still a bit of dried blood on his hands. For a moment he hesitated, but then he took Hayato's hand anyway, although he wasn't able to stand looking there.
