<P> Morgan Matthews (Lily Nicksay; seasons 1 - 2 / Lindsay Ridgeway; recurring season 3, main seasons 4--7) is the only daughter of Alan and Amy Matthews, the younger sister of Eric and Cory and the older sister of Joshua . She inexplicably disappeared after the show's second season and reappeared midway through the following season played by a different actress . In the episode of her return, a joke is made about her long absence . Upon her reappearance, she says, "That was the longest timeout I ever had!" With the introduction of a new actress in the role came a shift, not just in age, but also in personality as Morgan went from being the cute and innocent girly girl little sister interested in dolls and pretty dresses and perfume to being a more sassy, rude and sarcastic and more tomboyish character who delights in making fun of her brothers, especially Cory . In the series finale she, along with Amy and Alan, say goodbye to Cory, Eric, Shawn and Topanga when they depart for New York . </P> <P> Both Nicksay and Ridgeway appear as Morgan in the series finale of Girl Meets World . A joke is even made about the two, with Cory and Topanga's son, Auggie being frightened when he is comforted by both . </P> <P> Alan Matthews (William Russ) is the husband of Amy Matthews, and the father of Eric, Cory, Morgan, and Joshua . Alan, as the father of the Matthews children, provides guidance to his children . He has a quick temper, though when it shows up, usually through consultation with his wife, he often apologizes afterwards for words spoken in anger . In some later episodes, Alan does not support Eric in all of his ventures, and Amy, in turn, tells Alan that his coddling of Eric is the reason Eric has turned out the way he is . </P> <P> Alan was also somewhat of a "father figure" for Shawn Hunter . He explained to Cory in the first season that he saw a lot of his younger self in Shawn, and encouraged Cory to be there to help Shawn through his tough life . While there were times when he thought that Shawn was too much of a negative influence, such as when Cory and Shawn were arrested for underage drinking, he always cared about Shawn's well - being, even stating in the fourth season that he would "kill to protect Shawn from con men like you" to a cult leader who was trying to take advantage of Shawn's feelings of isolation . </P>
