Bluth, as well as half-sister of Lucille, who raised her and Michael to believe that they were twins. She is unhappily married to Tobias and together they are the neglectful and self-absorbed parents of Maeby. Lindsay never finished college, believing herself to be a dedicated activist, though she is actually vain, greedy, selfish, and materialistic (much like the rest of her family), mainly supporting current trendy causes for the social status and regularly holding extravagant charity drives that waste more money than they make. These causes have included opposing circumcision, anti-Iraq War protests, the removal of the 10 Commandments from a courthouse, the right to die (specifically regarding her brother Buster), and awareness about graft-versus-host disease (which her husband was afflicted with due to unnecessary hair transplants). Despite her outward confidence, Lindsay has rather low self-esteem as a result of her mother's constant hints and cruel jokes that she is overweight, which are untrue. Lindsay is portrayed as extremely resentful towards her sexually uninterested husband Tobias, with whom she ultimately agrees to an open marriage. During this time, Lindsay flirts and pursues relationships with many other men, with little or no success. She sometimes dates successful actors, such as Moses Taylor and Tom Jane. In season 3, Lindsay becomes interested in the family's new lawyer Bob Loblaw. In the last episode of season 3, it is revealed that Lindsay is not actually Michael's twin sister, or even a Bluth at all; she was adopted by the Bluth family to "stick it" to the Bluth family's rivals, the Sitwell family. Had Lindsay been adopted as the daughter of Stan Sitwell, she would have been named Nellie. She also discovers that she is 40 years old, three years older than she had previously believed herself to be. Feeling that her youthful allure has now escaped her, she becomes desperate to marry a successful man, and divulges to Michael that they are not biological siblings, hoping (with no luck) that she can seduce him. Creator Mitchell Hurwitz came up with Lindsay as the family's politically liberal figure, but Lindsay is also meant to represent a liberal who personally benefited from her politics more than she sacrificed, due to the image she built. This motif is continued in the series' revival and fourth season, in which Lindsay travels to India in an attempt to connect to her spiritual side and then tumultuously dates Marky
