Ally McBeal (1997) - 1x15 - Once in a Lifetime

Fish brings in a client, an 80-something world famous artist, who is battling his heirs to regain control of his estate. Ally and Billy co-counsel the case, and as a result of spending several late nights together, separately conclude that the artist's love of his recently deceased wife parallels their own relationship in many ways. Meanwhile, Cage begins to sense that Ally is losing interest in the possibility of getting together when she behaves in an overtly irritable manner that is obvious to the entire office. Fish loses his patience and decides to get to the bottom of Cage's problem with Ally.
