Mordred's reaction to seeing some orange thing flying around in the sky is one of confusion. Or to put it more bluntly one of “what the hell is that?” It looks kind of person shaped and she doesn't see one of those jetpack things Lance was using to get around. So can this guy fly on his own? Is it even a person? There's only really one way to get answers. Or well, okay, there's a couple, but she's not sure trying to throw her sword that far is the greatest idea. And if Mordred's thinking before doing something, that definitely means it's a questionable idea.

“Oi, flyboy! Get your ass down here!”

If Gohan bothers to investigate the source of the yelling, he'll find a short knight in a full suit of armor looking in his direction. Her expression can't be seen due to the helmet, but given her outburst, she's not in the best mood.
