[Starscream opens his mouth to answer Harry's question, then abruptly closes it.]

I don't... We rarely made contact with other planets, especially ones that were technologically backward.

[At Harry's explanation, Starscream perches his chin in one hand. He's still not sure exactly what being a wizard entails, but the last few days have been helping to stretch his suspension of disbelief.]

[However, one thing does cause him to hold up a claw in a "wait a moment" gesture.]

I was under the impression that only Princesses had fairy godmothers.

[Not that he's secretly watched Disney movies or anything.]

Yes, that would presumably be part of the modifications I mentioned. For instance, I used to be much larger than this. A titan compared to you humans.

[There's a smug smile on his face as he recalls being large enough to step on people.]

And I've seen how other captives have been modified. There was a... cat, who could speak like a human.
