The Feminum Mystique: Part 2 - S1-E6
Other mistake: On Paradise Island, while the Nazis are distracted by the quarreling Amazons in the water, when Wonder Woman jumps and lands beside Queen Hippolyta her boots are flat, but the heels soon appear when she rushes off with the bracelets.

Answer: Yes, on the first episode of season 2, she is shown on the island, when another plane crash lands, she says, "They sound different from WW II". Later in the same episode a woman gathers background information on Wonder Woman. The woman says, "From 1942 to 1945, she helped the Allies win the war."
