Fatima's Golem
I have this idea that the best use for Fatima's Golem is for it to be a thorn in the MIY's side.
What if once she completes that Golem, the MIY becomes unable to influence anyone in town (e.g. Sarah)?
What if when the MIY tries to track the thing interfering with his abilities, the Golem comes to life and attacks him? We know he's disguised as Sophia. This attack would create more drama as the MIY will feign innocence while the town's people turn on Fatima and possibly Boyd and Ellis as well.
Another theory is that it might mess with the MIY's shapeshifting ability. It would make for a good season finale/cliffhanger for Fatima to finish creating the Golem in the last few minutes of the last episode, which forces the MIY to change back to his original form in front of everyone.
The same idea can be done but without anyone witnessing Sophia changing back into the MIY, this could prompt him to leave the town, which causes people to look for "Sophia".
There's also the possibility that it the Golem might end up becoming a monster that will kill a lot of people, but it wouldn't be a fresh idea.
Other than that, it serves no other purpose than comforting Fatima after what she went through in the previous season without driving the plot forward, which would make it a waste of screen time.
What do you think?
