Crazy theory if wally stays in the show.

So we all know that we have two brainiacs that try to produce massive amounts of paranormal energy through experiments.

However one thing these eggheads also probably know is that part of einsteins famous theory of special relativity basically says that mass and energy are interchangeable, which means that energy can be converted into physical mass. Meaning that with enough energy it could be theoretically possible for a ghost to regain their bodies.

When you think about it their souls are basically just energy with a consciousness and it’s clear that this energy also remembers how their physical bodies looked and operated since their souls (energy with consciousness) still look and move just like their previous physical bodies. So maybe if the ghosts get zapped with enough energy said energy will convert into matter (aka their physical bodies). Essentially making them alive once again with the appearance and age of when they died.

Edit: just realized a day later but what if the reverse happened during that flickering of light and thats why simon is in the scar?
