"Huh?" Rodimus is shaken out of the thoughts he'd spiraled into to nod, pulling his hands back so he can move, and then he actually looks at Ratchet and his tanks lurch. Crutches. Ratchet's missing a leg and he didn't even know. He stares for a minute before he suddenly remembers what he's here for and moves - stepping around the chief medical officer.

"What happened to you?"

Tactless and crass, but he needs to know. Ratchet is a member of his crew, and as much responsibility he has to Drift, he has the same to Ratchet.
