[Contrary to Kiyotaka's reflection of what good the wound has done to their relationship, Hajime can't stop thinking about the alternative. If he couldn't have been there to protect him from this, he sure as hell can be thorough in following through on what's left. It's the least he owes him...

He ties the bandages off, and gives a firm nod, but doesn't quite back off, looking to Kiyotaka.]

I believe there's been a replacement nurse for a little while. As a facility for fighting, they at least have some limits for negligence.
