In this talk I will present a method for constructing two-point functions inspired by the hexagon proposal. This idea introduces the notion of "square form factors" that can be glued into a cylinder. Since cutting a square should give us two squares, we can write a consistency condition that heavily constrains such form factors. In particular, we are able to use this constraint to reconstruct the Gaudin norm through the forest expansion of the determinant appearing in its definition.
