During a field trip to Metropolis, the Gen-actives find themselves standing on the sidelines during the Man of Steel's latest super-heroic tussle. When Superman gets knocked through a few buildings, Fairchild places herself in the line of fire and takes the brunt of the impact. Relieved to find the unfamiliar redhead unharmed, the Man of Steel rushes back to battle — but not before leaving his cape wrapped around the dazed Fairchild.
After the fight is won, Superman and the Gen-actives are surprised to find that Fairchild has disappeared, taking Superman's cape along with her. Unbeknownst to them, Fairchild has come down with a case of amnesia and made a surprising — and breathtakingly incorrect — realization when she awoke with the S-emblazoned cape: She must be Supergirl!
