He didn't even notice it yet, the back of his head hitting the tree or, wall whatever. As he let out a little laugh, more out of awkwardness than worry.
"Mph-mnn-"
HIs inky tendrils of darkness slid around him again, consuming him. He was himself again.
"Nnn..."
He sat up, feeling awful. His face was tearstained, every muscle sore and mouth tasting like metal.
"I-I...I-I'm so sorry...I-I'm so so sorry I-I-I-I didn't mean to I didn't I-I didn't-"
He looked over and saw Kiri. He bolted upright,crawling over to him and shaking him.
"KIRISHIMA! Oh-oh god I didn't-I-I wasn't trying to-....I'm sorry...."
he pulled Kiri's phone out of his pocket, dialing 911. He was basically turning himself in....he didn't care.
