You know, thats a valid point, however.

Upon becomeing a Fae, The Seasonborn- then becomeing Fallborn, Springborn, Summerborn, or Winterborn, is clear enough-  as the Son of a human is a human, and the son of a fae is a Fae, its not like they change from seasonborn into pure blooded fae.

Though it should be noted 2 Seasonborn Do Not make a stronger season born offspring- its typically Weaker and is used as a Servant or slave.

A Seasonborn and a Fae will always result in the Fae's genes taking over, and the child would match the Fae parent.
