Dana Eleanor Caldwell (born August 18, 1976) is Adam's ex-girlfriend. They broke up after she moved to Seattle and they realized that long-distance wouldn't work.
The character Dana, and the actress portraying her, Natalie Alyn Lind, returned in the second episode of the seventh season "Dana's Back" airing on October 2, 2019. It was Lind's first appearance on the show since May 2017. She returned again in "Preventa Mode" (airing February 12, 2020), when she and Adam worked together to prevent their respected partners from going on a date at a roller rink.
Dana is a kind girl, however, Beverly does not really like Dana, as she is jealous that Adam spends time with her more than he spends time with Beverly, not because she is unkind. It is also hinted that Dana has mixed feelings towards Beverly. In season 3, when she moves to Seattle, Beverly has a nicer attitude towards her as she can not see Adam all the time.
