Alexander Greenwood is the son of Calvin Greenwood and Arisa Kisakra. He is married to Karolina Weiss, who is the reigning queen of 1919, making him the current king. He was born around the same time she was, and the two were friends as children. They were fed special growth food by Britt, and ran off together after everyone tried to teach them about being adults. They returned later, having eloped and making babies. Karolina later on revealed she was pregnant, and the two decided to keep the baby, relying on Addison and Amanda for help, since Alex harbored a permanent resentment towards his father.
