Now I'm defending my work devoted to one interesting comma, found by me personally, which I first thought was simply wrong, but then I fell in love with it, and I still am.
I need your assessment of what I think is correct about that "super" comma.
▪︎ Essential clauses cannot, as you know, be divided with commas, but this comma is put with them at the end, thereby it lets us know when the auxiliary, which is divided from its subject by a long essential clause, begins(it should help with reading); however, this comma is optional and doesn't have to be used.
Example: The cat running across the street over there[,] seems mysterious.
