Cells at Work! Season 2 Episode 4 English Dubbed >U-1146 and Normal Cell go to the small intestine, which is overloaded with Purine, but one of the lactic acid bacteria consumes it before deciding to stay there. Later, Normal Cell accidentally drops one of the remaining two into a storm drain. U-1146 sadly remarks that he has no authority over the immune response so he can't tell the other immune cells not to attack that bacterium if they mistake it for hostile, reducing Normal Cell to tears as he insults the immune cells for being heartless. Just then, NK Cell arrives.
