Ratchet, for his part, is still figuring out what to do with this strange new person he feels like he should hate. He knows it's unfair to blame everything that happened during the war on someone who doesn't remember, to take out any frustration and grief he has on someone who wasn't at fault, even if he only strictly wasn't at fault yet. And he knew how much Megatron had captured Orion's curiosity, back when.

It was just that Ratchet hadn't expected to like him quite so well.

So when Megatron had insisted on hanging around at the medibay and helping to set things up, Ratchet hadn't argued--just accepted, and gave him short jobs, and kept things as polite and professional as he could while he observed. He noticed his treatments were working, too, and that was an uncomplicatedly good feeling. His optics brighten a little as he watches the spring in Megatron's step as he comes into the medibay.

"Feeling better, are we?" His voice is dry, but warm, his optics flicking over Megatron clinically. "Told you."
