The Return of the Headmaster

With Sari evicted from Sumdac Tower, Porter C. Powell rehires Henry Masterson (aka "the Headmaster") to help run Sumdac Systems. Henry then decides to test his Headmaster on one of the new Elite Guard bots. Setting his eye on Sentinel Prime, he fakes a Decepticon sighting and takes over Sentinel's body, forcing Optimus and Sentinel to team up to get Sentinel's body back without Ultra Magnus finding out. Meanwhile, Bumblebee and Bulkhead try to be supportive to Sari.
