Aoba paused in his work when Kuro spoke. He could almost feel the pain as the other spoke. "That's no good..." He mumbled more to himself as he worked on cleaning him off. "You shouldn't talk if you can't. Don't hurt yourself more. I'll get to those injuries once I'm done cleaning." To get him as well as possible, Aoba was a little more meticulous today than he was before. "You should just stay quiet then. You're making these sessions worse. And I really, really hope they can't get any worse than this..." His voice held worry and concern, but it was low so the guards couldn't hear. 

Aoba focused, going silent for awhile as he moved from Kuro's arms to his back all the way to his legs. He didn't respond to much of anything he said minus a few nods and hums of acknowledgment. Gently, he cleaned up the blood around his mouth and gave him a towel to get comfortable on. "Alright Kuro. Time for the actual healing." He scooted and gently held Kuro's face in his hands. With a soft breath, his hands glowed dimly and he healed the wounds in his mouth. "There. That should help. And now you can talk." Aoba gave a smile and playfully and gently patted his cheek before going to heal both his arms, and then his legs. 

The process was slower this time as well. But Aoba didn't mind. It meant he could spend more time with Kuro. "I've gotten better with these." He managed to heal the wounds a lot faster than before. Something occured to him as he worked on the wounds that were able to close on his back. "You can't have another session, you'll die! You've lost way too much blood!" His voice rose involuntarily, making the guards turn quickly. 

"Oi! Is there a problem in there!?" Green hit the cell bars, scaring Aoba. The little angel jumped and looked back at the guards. 

"Sorry. It's- It's fine." Aoba looked away quickly and flinched gently when Green grumbled in annoyance. He sighed and then rummaged through his kit. "So, I managed get to sedatives to numb the pain." The angel looked fairly happy to tell him such a thing, before he had to tell him the next part. "Unfortunately, my next task requires burning... I'm not skilled enough to heal these. Sorry." His voice softened and he looked down at the needle in his hands. He really wanted to help, but he lacked the experience and he could only do so much for him. 

"But don't worry, I'll do the best I can." His optimism countered the small doubt and he held Kuro's arm. "I'm sure you can handle a small poke right?" He hesitates at first but carefully injects him with the sedatives, then waits for a response.
