I think that LILAC pics were the ones that I first became aware of Molly as the recurring young blonde girl in the purple uniform. I wasn't aware of other incarnations of her, so this is where she started out in my estimation.
With your "Kitten" pic, and hearing that Molly has had many appearances of different ages, and even started out as an adult; I suddenly worried that Kitten was the LILAC girl all along!
That's more like we're used of her! XD
(That, and her Orange Vixen uniform... XD )
