Meanwhile, Alexander is eating a spoonful of chocolate spread, and his teeth start hurting so he goes to get his toothbrush. He notices that it is missing, so he looks in his room and sees that Speech Boy has it. Alexander gets upset at Speech Boy. Speech Boy apologizes and asks Alexander if he wants the toothbrush back.
