....oh, btw, I also changed some variable names around to help make things more clear -'pverts' and 'tverts' have always confused me, so they got named 'ngons' and 'tpolys', respectively.

If I think about it, I can understand why you call it 'pverts' / 'tverts', as it's the indices of vertices that make up the polygon, but - that's exactly what a polygon/ngon/tripoly is - a storage mechanism for holding indices of vertices that make up the polygon :).
