Creepy Luz is a good Grometheus?

Ok so Grometheus is supposed to get the shape of witches fears, no one knows what happens if Grometheus get Human's fear. When it took Luz's fear it transformed into the Portal and a "Creepy" Camila appeared from it. Then, when it took Amity's fear, it became "Creepy" Luz.

Comparing both fears, the Human (Luz)'s fear looks totally more real than the witches (Amity)'s one.

When Grometheus took their fears' shapes it was just a shadow when became Amity's but it got a shiny blue light when became Luz's:

What if Grometheus got "bugged" and a part of it went through the Portal (created by itself). It found Camila and became the opposite of Witch Grometheus: instead of Camila's bigger fear, it became Camila's bigger wish, a "normal" Luz.

I think that Creepy Luz is good because Camila says "Thank you Luz, you always know what to do". Camila wouldn't have said that to our Luz since she wanted to sent her to the Think inside the Box Camp. + The letters Camila received "casually" arrived that day.

Maybe Grometheus thought Camila's wish was to receive Luz's letters so it gave it to her, and then it realized her biggest wish actually was to see a Normal Luz and then it became Creepy Luz the same way it became "Cats with human heads" as Luz's fear and then it became "Camila finding out" when it realized that was her actual biggest fear.

If that's the case, they could use Luz's fear again to make the portal appear.
