Rodimus doesn't spare a glance for the other medic at first, just assuming Ratchet's managed to pull in Flatline or someone else who'd ended up on this Cybertron. Not that he expects Ratchet to lighten his load - that's just not who Ratchet is. There's a betting pool on the Lost Light that Ratchet will die before he actually gives up the title of Chief Medical Officer to First Aid.

But there's no disguising that voice. Rodimus knows that voice. Sure, it's a lot less tired than the last time he heard it, but it's still Megatron. And when he looks up there's nothing but a half melted face looking back at him and that's the last goddamn thing Rodimus wants to see. Panic flashes over his face before it hardens into something unforgiving.

"What are you doing here? What are you doing?" He's tired and covered in energon that isn't his, but that's not going to stop him from not letting this happen. Whatever this is. "Get away from him."

The fact that he could be trying to help completely escapes him, because Megatron doesn't know how to heal anyone. He's just good at destroying and murdering and things that already happened to Drift.
