The comment from Jonah to Dina she talked about in her deposition, "you should get down on your knees...." sounds to me like a RETORT or reply, rather than a comment initiating conversation, or out of the blue. I suspect Dina made some negative comments about Rebecca and Max's injury occurring under her watch, that prompted that kind of reply from Jonah. Just my speculation, from reading all of the information over the years about how Dina disparaged Rebecca in public.
It's quite common for ex-wives to despise their ex's new love interest. In the case of a devastating accident like this, it makes sense that she would be angry and verbalizing blame in the early hours after the accident.
I've never believed the comments that they truly believed Max was improving. Even if we had Max's records to substantiate what the family was told about his condition and prognosis after the 30+ min cardiac arrest with complications during the stabilization, all they have to say is they "thought" he was improving, because denial of the seriousness at that point in time would be completely understandable by the average person.
Dina posted on her Max Shacknai website several years ago, the 911 run record to validate her claims that "no CPR" was done by Rebecca. This was back during her "Rebecca killed Max" campaign, which she NOW says she does not believe.She has only said this since being dropped from the lawsuit, which at the very least, seems odd (if I'm being generous).
I don't know too many lay people who can do effective chest compressions and rescue breathing (which was still recommended in BLS in 2011) on a victim with a head injury and an airway filled with passively regurgitated vomit. That was a severe challenge even to the EMS crew, with all their advanced equipment and suction devices.
There is no way that the complicated and prolonged resuscitation efforts would have been presented to Dina and Jonah as "smooth", or encouraging, or brief.
The run record tells a very dire story of a serious 8'-10' fall, with head and neck injuries highly probable, an airway filled with regurgitated vomit, inability to establish any kind of airway by paramedics at the scene (they could not clear the airway of vomit, ventilate him, or place any advanced airway modalities), inabiity to establish IV or intraosseous access, and complete cardiac arrest with compressions in progress. This necessitated diversion of EMS to the very small Coronado hospital to either pronounce Max dead, or get help to establish a patent airway, and enough of a cardiac rhythm, and lines, to get him to Rady alive (which, IIRC, is about 20-30 min drive?).
At that point, Max had almost certainly passively aspirated a huge lung/s full of stomach contents, which further complicated air exchange at the level of the alveoli, and made resuscitation even harder. The AR and med record review Dina paid for by Dr. Judy Melineck revealed Max struggled with a huge aspiration pneumonia syndrome from the time of admission to Rady. Aspiration pneumonia is like a chemical burn of the lung tissue. Not a single piece of any of this gives an encouraging picture, even without knowing what the exact head injuries were on imaging.
I know it supports Mr. Greer's theory that Max's parents thought he was improving. I just don't think there is any evidence we know of that supports this, other than their "belief". And if Jonah is still claiming he sent a VM to RZ about Max taking "a turn for the worse", then there is conflict in the whole story about how Max's condition and prognosis was understood by everyone who was in the know at that point in time.
