Tadashi was very proud of himself for not throwing up on the floor at the sight of their patient in all his under-the-armor injured glory. It didn't fully distract him from the weirdness of 'Brainy' being clearly more interested in the poor kid's symbiote than he was in the injuries themselves (somehow. They were pretty eye-catching), nor was it entirely enough to prevent him from making an alarmed noise when the injuries started to trickle red.

Maybe he should just throw up in the sink now and get it over with.

"I- I don't..." he swallowed hard. "What do you need me to do?"

Brainy seemed pretty confident here -- far more than Tadashi felt. He'd read about all this stuff, but it was less...this printed on paper in the safety of his lab.

But someone had to help, so he wasn't going to try and escape.
