Nightscream still believes Noble to be his friend. Blackarachnia brings back Silverbolt, and together they head off to rescue Optimus and Cheetor, who have been captured by Megatron. But Silverbolt has changed.
Megatron infects Silverbolt with a variety of Hate Plague virus, which he then passes to the other Maximals. Optimus realises they can only stop fighting and hating each other if they all work together - then wonders if Megatron is right.
The Maximals split into teams to search for the sparks. Underground in the original Iacon, Megatron reveals he's been misdirecting them, and steals the last of the oracle code from Optimus, but also reveals the location of the sparks.
