As best as I can tell, Charming's father agreed to give Rumplestiltskin a way to locate the Fairy Godmother, which led to him making her go *poof* in the episode "The Price of Gold" (two weeks ago), giving him the wand.
This episode also led directly into the events that we saw in "Snow Falls" (three weeks ago) with Charming and Snow White.
In other words, they decided to reveal the story in the Fairy Tale World in reverse order.
