"I am merely trying to help, Uchiha-san." Kabuto shakes his head at the obvious lie and concentrates his Chakra. The other should be feeling the strain, shakes and chills as he neutralizes bacteria, forcing cells to work harder to keep themselves active. A fine line between immobilizing his immune system enough to keep from damaging his lungs and enough to remove the infection. Perhaps the use of a medium to physically remove the bacteria...? No, far too small. It would be impossible.

"I am removing the infection you contracted while you were... how did you put it? Taking a walk."
