Reva is a necessary narrative device in Kenobi. Vader and the Grand Inquisitor used Reva as a means to an end when locating Kenobi. She was ruthless and would do almost anything to reach her goals, even if it was to the detriment of those around her. At first, she comes across as annoying and very extreme. We later learn the pressures Reva was under whilst fighting with her inner moral conflict, fearing that she is turning into the very thing she swore to destroy. It seems like Kenobi is also serving as a learning curve tail for both Reva and Obi-Wan, leaving fans to wonder what's coming next for the series and the characters involved.
