But Why?

So, you can maybe see why I dragged Dragonella into this. To paraphrase Wood's tongue-in-cheek credo: Never throw away a drawing pose that you can use again.

I had to wonder which came first between these two . . .

And I seem to recall more than just these two usages of a Cleopatra character, but haven't been able to find them.
The sketch I now had seemed to blend the playful and serious Cleos together.

Yes, but why?
