If Rumple saw a fairy using “his” wand, then he would certainly want it back.
Just a thought, but what if there is several weeks/months between Rumple sending Cinderella to the ball and Cinderella marrying Thomas? It would take time to organize a wedding so Lacey may happen between Rumple killing the fairy godmother and the wedding ball. It may also be a few weeks/months after the wedding ball that Cinderella finds out she’s pregnant. The weddding ball would take place after Skin Deep because Snow and Charming are happy together. Belle met Grumpy as dreamy after Skin Deep.
