Optimus: How is Ultra Magnus?

Ratchet: He's going to be alright.

Wheeljack: Finally, some good news from you.

Ratchet: That's a great attitude. I've got to tell you, if I was getting this news, I don't know if I'd take it this well.

Optimus: But you said he was alright?

Ratchet: Yes, he's lost his left servo. So he's going to be "all right".

(Technically he actually lost his right servo, but eh. What are details?)
