Straight up the relations would send a social worker to therapy.

Hayley is trying to do Elijah when she’s had a kid with his brother.

Klaus seduced and wanted a relationship with a woman his pseudo son liked and had sex with for a while.

Marcel has had a repeated sex loop and eventual marriage with Klaus’s sister and he’s the pseudo son.

Freya married a woman she essentially held hostage after welshing on a deal already made.

Kol is out here getting with Marcel’s pseudo kid Davina.

I love all these relationships to death but my lord they are a whole Pandora’s box that would make lesser men mad. Legitimately the only normal relationship is Finn with that red head and still even Finn tried to get with Cami one time.
