if this isn’t the opening message in the v route im gona-
They gave Dean the big "no" line when Cas got stabbed. They had Dean be the one to not be able to say Cas was dead (Sam could. And dean had no problem saying it about the others). And Dean was the one to prepare Cas's body. They showed Sam grieving which was very heartfelt but let's be honest, Dean has been the focus of Cas's death from the moment Cas got stabbed until they burned him. Idk how anyone can ignore/deny that there's a reason for that. They could've cut/diminished a lot of that.
