5 people linked hands to save the dog, but there are only 4 in the statue...

He's made up.

That's not necessarily the same thing as not REAL. But he, just like all her friends who show up in her room before her adventure as toys and figurines, exist in relation to her, in response to what she wanted and needed. She told the story and there he was, there he always had been. But she's a teenage girl who doesn't know what she wants yet, and Jareth kind of pays the price.

"but the king of the goblins had fallen in love with the girl, and had given her certain powers." He's an archetypal oxymoron. He's both the dastardly baby stealing villain and the royal love interest trying to relieve the heroine's suffering, Cinderella style. He's fucked either way by being both. She doesn't know if SHE wants to be the villain or the heroine until he shows up and then she decides on the heroine, so he has to sneer and menace and challenge but it's too late for him!! it's too late, The King Of The Goblins Had Fallen In Love With the Girl, he's Cinderella's prince too and he has to try, he gives her a poofy dress and takes her to fucking goblin prom, sweeps her around the room like a music box with perfect posture and room for Jesus.

But it doesn't work buddy, it can't work. You're just a story for a teen girl to grow up in, and as the villain you have to be defeated. He's so complex because his tropes contradict themselves, and he doesn't understand why he has to lose when he was only doing the job he was given. In his last scene he is pale as death with shadows under his eyes, backing away and begging for his happy ending with nonsense mishmash promises that belong to both halves of him.

Hello my baby hello my honey
