Lexa Doig deu à luz uma filha em setembro de 2004, durante a temporada final de Andromeda. Em vez de "drama", sempre assumi que essa era a explicação para o papel reduzido dela.
O Wiki Andromeda parece apoiar isso:
Due to Lexa Doig's pregnancy during the filming of the fifth season of Andromeda, writers re-wrote part of the season finale so her character could be excluded from most of Season 5. The character Doyle was written to replace her during this time. Rommie's new body is thicker and bustier than her old body, due to the physiological changes that occur in a woman during pregnancy and child birth, and upon being asked by Dylan how she felt, Rommie answered "Sturdy."
