Ky would have definitely protested a visit to the hospital, no matter what kind. He didn't even think a bandage was really necessary, but Potemkin is already dashing out to grab the items. While he's out, Ky decides to unbutton and remove his shirt just out of convenience. He's going to end up taking it off later anyway (since there's little use wearing a ripped shirt), he might as well do it now if Potemkin is going to go this far.

When the other man returns, he glances at the antiseptic in Potemkin's hand and makes a face. Must they?
