Like most long-running hit series, "Grey's Anatomy" faces the problem of keeping the pot boiling - how to maintain interest in an episodic (in this case derived from tried & true soap opera romantic conventions dating all the way back to radio serials) storyline whose high points are largely in the distant past, what with the inevitable churn of major characters - title roler Grey is still standing but not too many others.
This particular she said/she said courtroom battle segment solved the dilemma by diverting away from the show's Prime Directive of hospital pathos - life and death situations, in favor of a very human and very modern story about child custody. Having the two lesbian characters as warring moms, with dear Grey intoning rather pretentious allusions to King Solomon's solution in her voice-over narration, is the new wrinkle and quite well handled.
In fact the script had me guessing (wrongly) right through to the end as to the judge's decision in the matter and it was also fun watching surviving cast members like Chandra Wilson and Kevin McKidd (who also ably directed the show) have to take sides as to which heroine they supported with court testimony in the case. Balancing this stagy footage was a quite effective dollop of the necessary (and relevant) hospital antics, concerning the fate of a premature baby still in the womb whose mom is inadvertently being neglected by one of our heroines who is in charge of her care.
Ultimately the hit, which I recall watching breathlessly every Sunday night its first season as a breath of fresh air to broadcast TV, will have to give way to fresher concepts, but it is satisfying to witness life in the old body still.
