Interesting. Wrathion tilts his head, considering that.

"Yes," he admits. "Fire conjuring is the least of my abilities. Elemental control is common enough where I am from that most people wouldn't give it a second thought."

Which is why, for him, it isn't a particularly impressive form of magic. Then again, as the Doctor says, if you haven't seen it in that exact way he supposes it is interesting. Wrathion does like to learn, he supposes he can see that he'd be at least curious about someone conjuring fire in a way different to what he knows.
