I prefer the Clone Wars Multimedia Project over TCW and affiliated media, but I like Ahsoka as a character, so I like to think she existed. In my head-canon, she has the same personality as her Rebels version and the same physical appearance as her own adult version that is seen in the Mortis arc in TCW. She was trained by a random master who has never been seen in the films and was never part of the Council, one master among many, and was appointed as a Jedi Knight before the Battle of Geonosis. During the Clone Wars, she was 22 years old (the same age as Anakin in ROTS) and was in command of her own battalion of Clones. She fought heroically during the war, as she was convinced that it was necessary to restore peace to the Galaxy and defeat the Separatists and the Sith. However, during the course of the war she began to mature ideological and philosophical differences with the Jedi Order and begun to convince herself that the strict rules of the Order were wrong, so much so that she started to develop feelings for one of her commanders. She even planned to leave the Order and go her own way after the war, but unfortunately she was killed during Order 66. She never had anything to do with Anakin, Obi-Wan, Padmé, etc.
