|"I brought my research on the prophecy of the Green Ninja. I thought maybe we could go over it together."
It is currently unknown if this topic can be considered canon. You can help by examining the relevant installment to see whether it contradicts the TV series.
Rachel Sparrow became a producer, creating the wildly successful show, Most Ultimate Extreme Ninja Challenge Ever, her show becoming a favorite of Ed's to watch.
Rachel would welcome Jay during his attempt to finish the Gauntlet of Humility, acting as part of the audience and readily encouraging him. Impressed by Jay's charisma regardless of his failure, Rachel would hire him as the show's new host after Fred Finely quit his job.
After Jay quit his job, she presumably hired a new host in his place, as she did with Finely.
