You and Reiner had been set up to be partners during combat practice as a part of cadet training.

You threw a punch at Reiner and then he tackled you to the ground. You soon noticed a little blood escape Reiner's shoulder after he scraped his shoulder on the ground by accident after tackling you.

You opened your mouth to tell him when you suddenly saw steam come out of his shoulder...

Thats not normal..

Everyone else was busy practicing their fighting skills with their partner so no one else had noticed the steam too.

Reiner looked at his shoulder and chuckled nervously and then looked at you with a nervous grin on his face.

What do you do?
