He isn't King Zaiver Illegimate son, did you check out what episode 16 is about

For episode 2.16, the guest role of "King Xavier" is being cast. he's 45, has a mean sense of humor, and worries about being able to maintain his extravagant lifestyle since gold has become more scarce in his kingdom. Also being cast is the co-star role of a 20-something "Prince Henry" (Regina's father as a young man), whose marriage could change King Xavier's fortunes
