Yamamoto blinks, he can see that most of the injuries aren't too bad, they should be able to at least make it back to a clinic, get fixed up and they will be just fine. He is not too worried, they have certainly both been injured more severely and been involved in fiercer battles.

What concerns him the most, how Gokudera is acting. "We need to see a healer..." Not because of the injuries, no a regular old doctor could fix those up but maybe one can help Gokudera he thinks as he reaches out, winding his fingers around the Black Knight's sword. The swordsman in him can not resist testing its weight, he does not care for it, too heavy, it would hinder his movements. He'll stick with his own style.

He reaches in his pocket and pulls out the vial they were given, he pours it out and has to chuckle when the whirlpool appears, swirling wildly he drops the sword in and it is swallowed with a quickness, the water, seeming to sink into itself and disappear.
