Armoured, Starscream. The one with the big head is yourself.

It was more the cotinuing overdramatic flopping about that convinced Jetfire Starscream wasn't hurting as much as he claimed he was, than any actual lack of concern. Because really, he was concerned, but Starscream required some amount of interpretation.

"I think you would be... ah, moving about less if it was." Jetfire shook his helm and kept his grin under control and if the pain really was worse, he'd probably be complaining even more...

Since Starscream knew he could do that, with him. Which was a bit frustrating and annoying perhaps, but at least he could temporarily leave if it became too annoying.
