While in London, Wonder Woman was summoned to help a young lady called Zola from the minions of the goddess Hera and after Diana defeated the enemies, she was informed by Hermes that Zola was pregnant with Zeus’s child, which caused Hera’s wrath. Diana then took took Zola and the injured Hermes to the island of Themyscira, home of the Amazons, where Hera’s wrath reached them in the form of her daughter Strife. Wonder Woman used the Lasso of Truth to stop Strife from hurting the Amazons, but it caused her to reveal the fact that Diana and her were sisters. The next day, Diana learned from her mother that she was in fact Zeus’ daughter and, hurt by her existence being a lie, she decided to renounce the name Diana, and swore never to return to the island again.
Steve Trevor died at the end of Wonder Woman after sacrificing himself to ensure that a plane full of deadly gas couldn’t harm anyone on the ground. Is this Steve Trevor the same Steve Trevor that we saw in Wonder Woman who was transported to 1984 because of something like time travel, a descendant of Steve Trevor’s who is also named Steve Trevor (and looks exactly like Pine), a clone, or something else entirely? (It’s a comic book movie, so anything is possible.)
She asked him who he was, but before he could answer, the two noticed several boats coming through the island's forcefield. Steve noted that he was one of the good guys and the people on the boats—Germans—were bad guys. Having noticed the invading ships, the Amazons quickly gathered on the cliffs above the beach. Hippolyta ordered Trevor to move away from Diana, but forgot about him as the German soldiers began to come closer to shore. She took command of her army, ordering the archers to fire on the boats. Diana and Trevor took cover behind boulders on the beach.
