In OOT 3D if you go into Ingo's room you can find resting atop his shelf a portrait of Ganondorf.
Why does he keep this? It is clear he likes the way things are being run but to have a painted picture is a bit much. I doubt Ganondorf posed for his portrait just to give to Ingo so it is possible ingo is actually a talented artist and painted the picture himself remembering every exquisite detail of his beloved king. He even intends to give Ganondorf Epona as a present. Ganondorf already has large black stallion and Epona looks a bit small for him to ride. So Ingo obviously meant to give her as a pet. Now I don't think it is common practice to give a pet to a monarch usually to someone like that a human sacrifice or free milk would be the most suitable way to show respect which leads me to believe that Ingo is actually in love with the Demon King and intends to declare his love by making a gift of Epona to him.
