He wants to take the baby, upon birth, away from Lwaxana to be raised in an all-male environment. Lwaxana does not want to be separated from her child. Odo discovers that according to Tavnian law the son belongs to the mother's husband, not necessarily the actual father. He proposes that Lwaxana divorce Jeyal and marry Odo, so that Jeyal cannot claim her child. This scheme is complicated when Jeyal invites himself to the marriage ceremony. The Tavnian marriage ceremony requires that all present be convinced of the legitimacy of the feelings of the couple, meaning that Odo will have to convince Jeyal that he is truly in love with Lwaxana in order for the marriage to be legitimate.
