I think Martinez piped down because it's not in the State's best interest to save her from drowning.
This jury seems to be paying attention. Strip away the 99% fluff and nonsense and ridiculously detailed carp droning out of her mouth and what you have is 1 percent distilled venom. She's trashed every last person in her life she's deemed "significant." Every single one. She's reduced even love-smitten Daryl to a drunken smoking business investor. Mom has deep bus tire treads all over her back, and her dear dear Bobby? The fellow is dead and like Travis, can't defend himself against the accusations of real abuse she's slinging.
I think Martinez believes her self-serving despicable trash talk is doing more damage than any objection he can raise right now.
