While helping protect Pridelanders with Pride Rock's guards who traveled to save others and her cousins African Wild Dog who guarded Pride Rock protecting the royal family, Reirei didn't mind if she was the rescuer or the assistant or once in a while if her cousins also helped Kion's small team Reirei accepted being the squire during difficult rescues.Reirei had enough sympathy about losing someone you loved that she was quite willing to look after Timon and Pumbaa for their friend who was now the king Simba. Reirei herself had lost siblings when she was a pup.
There were even times an Outlander was sneaky so Jasiri, Reirei, and Bhati were cooperating to save a Pridelander who lived near the Outlands altogether, especially during long outings that Simba invited his whole kingdom to. This was a big issue with Janja mean clan, but there was also Shenzi's clan, and Zira, as well as the crocodiles when they were sneakily walking on the grass behind a herd. This problem also included Kenge.
Finally welcome to the Pridelands this young adult jackal Reirei was freinds with several of the birds from savannas jungles and deserts. Reirei helped Rafiki stay in with golden wolves since they could run all the way up to southern Europe and Asia too. These reports from Rafiki's paintings that he told Reirei sort of helped Simba with solutions of nature but he had relatives all the way up to Greece so he let golden wolves report news of nature from the north before making his decisions. Reirei herself told lions in Southern Africa's states Simba's new plans.
