Kaitlyn lost the assistant job to Eve the following week. On August 20, Kaitlyn won a battle royal by lastly eliminating Eve to become number one contender to Layla's Divas Championship. Eve then started acting disingenuous towards Kaitlyn and Layla, leaving them confused. At Night of Champions on September 16, Kaitlyn was attacked by a masked figure, causing her ankle to get injured in the storyline and forcing her title opportunity to get forfeited to Eve. Kaitlyn later stated that the attacker was blonde, leading to Beth Phoenix becoming the suspect. On October 8, Kaitlyn was defeated by Eve in her first Divas Championship match, and was afterwards saved by Layla after Eve attempted to re-injure her. Kaitlyn later confronted Eve about her attacker, revealing it to be Aksana, who was instructed by Eve to attack her at Night of Champions, and ended in a brawl also involving Layla. This led to a tag team match on October 26, where Kaitlyn teamed alongside Layla in a loss to Eve and Aksana after Kaitlyn was accidentally kicked by Layla. Kaitlyn received another shot for the Divas Championship at the Hell in a Cell event, but was again defeated by Eve in a triple threat match, also involving Layla.
