Lana Lang spies Clark Kent changing into Superman and deduces once and for all that Clark is Superman. She confesses the truth to him and asks him to use his super-hypnotism to erase the secret from her mind. With that request, Superman realizes how generous Lana is and discovers that he is in love with her. [1]They get married soon after and Superman flies Lana to his Fortress of Solitude. While there, he gives her a special serum to drink. This serum “containing a speck of the rare element, korium-66-beta, will give you super-powers because you have blood-type A! It wouldn’t work for Lois because she has blood-type O!”
