The April-May Hiatus was a shorter hiatus of Drama. It lasted from April 11th, 2016 (right after Total Drama: Thunder Falls ended) until May 29th, 2016 (when Total Drama: Revenge of the Antagonists premiered). It was an unexpected hiatus, according to me (Ethan Bump, the creator).
Reason for hiatus Edit
I really don't know why I put Drama on hiatus. It just seemed to happen. I got quite busy with other work and fun and the series went on hiatus for over a month.
