The parentage of John Dutton Jr. is uncertain, but it is likely that he is the son of either Spencer and Alexandra or Jack and Elizabeth. It has been disproven that John Jr. is the son of John Sr. and Emma Dutton. Elizabeth suffered a miscarriage in 1923, leading to speculation about her being John Jr.'s mother.
However, it is more probable that Alexandra is pregnant with John Jr. since she expressed a desire to start a family with Spencer. Jack reassures Elizabeth that they can still have a purpose in life despite not having children.
