Synopsis:
While secretly performing good deeds as Supergirl, a boy from the Midvale Orphanage, Dick Wilson, takes a picture of her. He suspects Linda Lee is Supergirl, when he sees her turn in a report that she finished at super-speed. Linda makes an excuse that she had a copy of the finished report elsewhere, but Dick is not convinced.

While looking for minerals for Geology class, Dick tricks Linda by throwing a dummy of himself off a cliff. Linda’s X-ray vision ignites chemicals which Dick coated the dummy with. Linda causes lightning to strike the dummy to cover her mistake. Dick is still convinced she is a Supergirl.

Dick tries to trick Linda again with heavy dumbbells. Linda falls for the trick, but her powers allow her to once again cover her mistake and protect her identity. She is distressed over the situation when a Supergirl robot arrives to perform amazing feats at a show. Dick is now convinced that he saw the Supergirl robot sent by Superman, and that Supergirl does not exist.
