Something doesn't quite jive with the "Divide and Conquer" date. They have the air date listed as 04/17/11, which is a Sunday. It's likely to air 04/22/11 in it's normal Friday time slot. The only episode that receives a description is "Sick Mind":
Optimus Prime becomes infected with a Decepticon plague.
TV Guide has also updated their Transformers Prime listing. While they have only listed one of the aforementioned episodes, "Sick Mind", they do offer a little bit more information in their description:
A Decepticon plague infects Optimus Prime, so Arcee and Bumblebee sneak onto the Nemesis to find the cure.
