The Dev Insights from her kit reveal in March 2020 state:
Inspiration:
This Rey primarily represents her journey through Episode IX and still hasn’t fully decided on her path. This isn’t the Rey you see at the end of the movie so she’s not “Rey Skywalker” quite yet and we wanted to keep the emphasis for this character on just being Rey (hence why her in-game name is Rey.)
So I take that as the character we see in game representing the point where is she is torn between following the path of the Jedi and submitting to Palpatine in order to save her friends. It is then later that Ben Solo joins her against the Emperor and she is able to achieve both.
