Hi Gabriel,
GBU2.
I hope I get this "right" this time.
[spoiler] To get "leader", there is "something hanging" over on the ledge by the love shack. To get this "something hanging", take a villager, child or adult, and move them "over" the ledge area again, til you see "so and so is interested in "something hanging and this is what is needed'. "If" you "have what is needed" to get the "something hanging", take that "what is needed" back to the ledge and drop them on the "something hanging."[spoiler]
GL.
GBU and yours.
