The "Lies" story arc runs parallel with and explores Diana's search. No longer able to get into Mount Olympus, Diana tracks down Barbara Ann Minerva, the Cheetah, to get help. Cheetah agrees to help in exchange for Diana aiding her in killing the god Urzkartaga and ending Minerva's curse. The pair battle their way through Urzkartaga's minions, the Bouda, and defeat Andres Cadulo, a worshiper of Urzkartaga that planned to sacrifice Steve Trevor to the plant god. Once reverted to her human form, Minerva agreed to help Wonder Woman find her way back to Paradise Island. During this time, Wonder Woman reconnects with Steve. Minerva eventually realizes Paradise Island is an embodiment of emotion instead of a physical place, so Wonder Woman and Steve head out to find the island. They succeed and Wonder Woman is greeted by her mother and sisters, though Steve senses something is wrong. Wonder Woman comes to realize nothing is as she remembers and, upon using the Lasso of Truth, discovers everything she thought she knew was a lie: she never really returned to Themyscira after departing with Steve years earlier. The revelation shatters Diana's mind and she is left nearly insane. Veronica Cale, a businesswoman who has been desiring to find Themyscira and the leader of Godwatch, sends a military group called Poison after her, but Diana's state has left her vulnerable and oblivious to the danger she and Steve are in. Steve wards them off long enough for them to be rescued, and reluctantly places Diana in a mental hospital so she can get help. While there she comes to grasp the reality she thought she knew was false, eventually coming out of her stupor and able to rejoin the others in tracking down Veronica Cale, who is trying to find Themyscira.
Thus although by the modern depiction her accomplishments at the time seem ordinary, in that era they were more so. Diana Prince was originally an army nurse, but quickly attained the rank of lieutenant in Army Intelligence. This was partially a creative convenience so that she could be close to both Steve Trevor and received information which she needed to pursue her superheroics. In the real world though, this role in Army intelligence, even as the secretary to General Darnell, was still a rare position for a woman to hold in society. At this time as well, the character had her only real sidekicks in her history in the form of Etta Candy and the Holliday Girls. These characters gave the Wonder Woman a degree more of levity while also allowing the writers to focus on some issues which were more related to women. When Marston left the character, the strong driving force of the character to act as a strong moral guide and role model for female readers left as well and the character became more sensitive to the forces driving the industry as whole. Thus Wonder Woman changed somewhat to a more stereotypical woman. Her main interest was not always fighting crime, but for a time it became all in the interest of keeping Steve Trevor happy and interested in her for marriage. Also the backup stories featuring the Wonder Women of History were slowly phased out and replaced with features on marriage customs from around the world and trivial facts on random household objects.
Diana is a very kind, loving, compassionate, and strong-willed person, who, while initially somewhat naive, has become all the wiser through her time in Man's World. An outspoken egalitarian, she fights for what she believes in and generally for the betterment of mankind through love and mutual understanding, as taught to her by her mother and fellow Amazons. Growing up, Diana also proved herself headstrong and determined to do what she wanted, such as training in hand-to-hand combat under her aunt Antiope's tutelage despite her mother initially forbidding it. In this way she is quite stubborn; if she believes something is the right thing to do, then she will do it - as evidenced by her attempt to leave Themyscira without her mother's permission and insistence in attending Ludendorff's gala despite Steve telling her not to. Alongside her kindness and compassion, however, Diana was also a very naive idealist when she first arrived in "Man's World", blindly believing that all men were corrupted by Ares and that the World War I Central Powers would simply abandon their sinister ways if she killed him. This blind naivety also translated to explicit indignation whenever she was treated with disrespect due to her status as a woman, such as when she was ignored by members of the War Office. Alongside this, Diana also voiced her opinions rather bluntly upon her arrival, such as when she perceived Etta Candy's job as Steve Trevor's secretary to be akin to slavery (which earns Diana Etta's admiration). Despite her outspokenness and behavior in Man's World, however, Diana remained caring and compassionate, as demonstrated by her initially rocky relationship with Charlie and willingness to step into No Man's Land to save the village of Veld.
It was later retconned by Gail Simone that Wonder Woman's outfit design had Amazonian roots. During a flashback in Vol. 3, Hippolyta is shown issuing orders to have a garment created for Diana, taking inspiration from the skies on the night Diana was born; a red hunter's moon and a field of stars against deep blue, and the eagle breastplate being a symbol of Athena's avian representations.[volume & issue needed]
