William "Will" Horton, III is a fictional charcter from the American NBC Soap Opera Days of Our Lives, played by Guy Wilson. Will debuted on-screen during the episode airing on November 16, 1995. He is the son of Sami Brady and Lucas Horton, but was originally passed off as the child of his uncle Austin Reed. As the character aged on-screen, he endured a "turbulent upbringing" due to his mother's love life. Will has always wanted his parents to be together, so he could be like other children he knew. This resulted in Will becoming "moody and suspicious".
