Optimus was no stranger to the threats of war—death, trauma, and illness. Yes, even Cybertronians get the worst of any sickness, far worse than any organic could ever endure. It was only three words.

The Cybonic Plague.

During the scavenging, you, Optimus, and Ratchet had searched the rusted ruins of a crashed Autobot ship. It crushed him knowing fellow brothers had sadly died inside, but along with them, their lifeless frames brought dangerous infections. Unfortunately—you had caught the Cybonic Plague instead of him.

Now he was deathly worried. Ratchet couldn't find any information on the cure to such a painful illness—you've grown worse since returning to the base. Your face was etched in a black mass, giving you a more zombified look.

It was clear that they had to steal the cure. Despite the Decepticons having the only recipe for said cure, Optimus ordered Bumblebee and the others to sneak onto the Nemesis, and reach Megatron's stasis-locked body to enter his mind and get the information for it.

Now, it was a waiting game. Optimus dearly hoped the others would succeed with the mission in quick succession, but there was no guarantee. He knew how stubborn Megatron was, how stubborn he's always been. All he could do was stay by yourself as you laid upon the beer Ratchet had offered—feeling helpless as he did his best to comfort you.
