Gokudera watches, still just holding onto the sword, but he’s not sure where to go, so this is all according to how Yamamoto guides them. He stops at the question, tilting his head a little. The blood is visible, but he doesn’t seem to be in much pain. Honestly, he’s sustained worse wounds that were self-inflicted. The cut on his shoulder isn’t sever.

“Woof.” He answers, then offers the Black Knight’s sword to the swordsman. Seems like an appropriate thing to do.
