Yeah I was wonderi g if they were going to be human or what.

Why couldn't each of them be half and half?

But they are also human and it makes no sense that the human attributes of both parents would combine in the child, but not the wesen characteristics.

By the negative response of their parents, prior to their wedding and the purity police that went after them after they got married which was one of the reasons Juliette decided to drink the potion to help Nick get his Grimm back, we can all assume they would be a type of hybrid between the species.

I think they would be hybrids as well. The outrage of the community makes no sense if all wesen parents had full blooded children of one wesen species or another.

They are probably hybrids

I hope in the spinoff(that is if there will be one) that triplets will be a mix between blutbad and fuchsbau.I hated how in the last episode they only showed adult Diana and Kelly and only mentioned the triplets.I hope I see them in the spin-off!
