However, there could also be room for her on RAW if she is the one who helps Naomi to retain her title later tonight.Jax and Naomi are part of the Anoa'i family, and tonight the odds will be severely against the Women's Champion because Rhea Ripley and IYO SKY have developed a friendship and are both looking for revenge.Will Nia Jax be revealed as Naomi's Plan B at SummerSlam?Naomi noted that she would be walking out of SummerSlam with her World Championship "by any means necessary," which could mean that she already has a Plan B in place.
