The Snoke vat is too silly to keep.
Why is he continuing to make Snokes? Why make more than one to begin with? Did Exegol have makeup artists or surgeons that carve up his scars?
Perhaps there might be a compromise in there? Have the Palpatine clone be front and center but maybe have one of the background clones be Snoke? Of course it doesn’t matter either way, leaving the question ambiguous was honestly the best way to go since if the point was he made Snoke then it would’ve made more sense to have a single Snoke clone in a vat and not the pile of them.
