On Wednesday, the Twitter parody account My Little Pony Facts shared an email response that they had received from a Hasbro PR representative. Although this post was pretty out of character for the account, it wasn't a joke, and the email is almost certainly real.
According to this email, My Little Pony: Tell Your Tale is ending, and its biweekly schedule will only continue until October 17. This means there should only be two episodes left: season 2 episode 22 on October 4, and episode 23 on October 17.
