Remember, Reed Burkhardt's body was found in the car crash beheaded. Kelly confirmed that Reed was the driver. of course, if Renard was the father, then Nick would be part hexenbiest. also, renard would have had to avoided the people trying to kill them and placed a decoy, all between the moment of attack and leaving the house. i have no doubt that he was able to disguise himself as a wesen and a royal from Kelly, although perhaps not royalness.
