"I didn't get in his way, he was just standing there when I ran into Megatron." They were having a conversation that Rodimus interrupted is the accurate implication. It would have been nice for Ratchet to tell Rodimus that, however, because he absolutely tries to move it and makes a frustrated sound when it doesn't do what he wants. Ugh.

"What?" It doesn't register that Ratchet's talking about the damage he did to himself into a moment or two later. "Oh, no I got that when I set myself on fire to get him to let go of me after I kicked him in the face. Before Megatron started shooting at us. Did I mention that?"

To be fair, Megatron's presence is probably what saved his life but. Details.
