When it's obvious the portrait of the Brady kids is beyond fixing, Jan tells the rest of the Brady kids that the photographer Gregory Gaylord was so mixed up that he lost the negative, and that all the Brady kids have to go back to the photography studio for their photo re-take for the replacement portrait. After it was discovered by Mike that a replacement portrait of the Brady kids shows Jan wearing her glasses, Jan not only confesses to Mike about not wearing her glasses at the time of her accident, she surprises him that she sold her bicycle to pay for the replacement portrait.
