If there's one thing that Optimus can read about Ratchet, it's when he genuinely likes someone. Thankfully, though, it's not something Optimus will say outright. But it's nice to see him taking to Megatron. He'd be lying if he didn't feel the same about the miner. Something he'd always liked about him, even back then.

Not all things change.

"Watch over him for me, Ratchet. I know you will do so yourself, but...extra from me."

...

"I want the best for him."
