In a fanfiction, Ratchet and Optimus could be sent on a secret mission. They are alone, away from the rest of the Autobots. This gives them a chance to have more personal conversations. They might discuss their hopes for the future of Cybertron, their fears about the Decepticons, and their memories of the old days. The story could show how they support each other not just in battle, but also on an emotional level.

This would require them to work together closely, using Ratchet's knowledge of history and Optimus's leadership skills to navigate this dangerous new situation.
