how does the relationship between puck and oberon develop throughout the play

Oberon is the master of the island and definitely influences the goings on in the play. He is, more or less, master over Puck. Unlike Prospero and Ariel in the Tempest, there seems to be a friendlier dynamic between the two. Oberon uses Puck as his sounding board and confidant. At various times Puck is messenger, clown and servant. He carries out Oberon’s wishes but also puts his special spin on them; Puck is a trickster after all.
