It was his fault, he knew it was. He sent you in a building withouth checking first, how stupid of him. He thought all the enemy were dead, he didn't know they left a gift behind. A bomb.

It exploded just when you entered from the door, the shards hitting your body, burning you. As you layed on the infirmary bed after the mission, lucky to be still alive, he was sitting on a chair by your side. He was asking himself why it happened to you, he didn't want to lose you.
