It certainly was. I only regret that your performance was cut short. I'm not easily pleased, but I was quite taken with it.

[Kuja certainly doesn't sound like someone easily pleased. He sounds like a particularly uppity noble. Then again, Laslow's spent a lot of his time around surprisingly grounded nobles, so he might have more reasonable expectations of Kuja than the man actually deserves.

He, at least, seems to be referring specifically to Laslow's dancing.]

And yes, it's magic. A rather cunning utilization of the Float spell, if I may say so myself.
