Later, Joey came and they asked him what he would do if he had super powers. As a result, Joey heard what he would do if it was inhuman.
Joey said he would kill himself, and everyone else thought it was strange. He asked him why, and he replied, if his little brother can't be used, why is he still alive?
Ross knew that Joey misunderstood them, so he explained that he was not inhuman, but had super powers.
As a result, Joey misheard Ross again and said that Ross was inhuman, so he apologized to Ross.
