More: Family of Gabe Watson speaks 7 years after his wife died while scuba diving in Australia | al.com
"Something happened, Stutz said, and they separated.
"I didn't know what it was at the time, but just watching what I had in front of us, that maybe,
I don't know, maybe she'd pulled (the) regulator out of his mouth, or kneed him in the groin. They split apart. He went to the surface. I assumed to find help."
OK, I was not able to confirm this statement from Dr. Stutz other than from the story of Watson's family speaking out, however, I will go ahead an assume that it is a direct quote from Dr. Stutz' transcript with police. (If the prosecution can leak quotes from the transcript, the defense can too.)
As ItsBruce has strongly argued, the defense will probably make the argument that Dr. Stutz never saw Watson turn off her air. The prosecution will probably argue that Dr. Stutz does not state that he saw Tina pull Gabe's regulator out of his mouth. It does sound like he saw some kind of struggle where something like that could have happened, but he can't go far enough to say that he saw it happen because Gabe's position blocked that view of events. Here is another quote from Dr. Stutz about that moment in time:
"His arms were around her, like an embrace ... his arms were under her armpits and I thought he was trying to bring her to the surface.
Then they split apart, I don't know why –
it was hard to see because he was between me and her. Then he headed to the surface and she was sinking looking straight up at me – it was terrible."

The defense should pursue Dr. Stutz' recollection of what it was he thought he saw that made him think that "maybe" Tina had knocked Watson's regulator out his mouth or kneed him in the groin (accidentally?)
Noteworthy for the prosecution on this issue is there is no statement from Dr. Stutz that he saw Watson lose and then replace his mask as Watson stated. If you read the quotes from Dr. Stutz in the above story, his statement reads like he never took his eyes off the incident as it was happening with the exception of getting to the dive instructor, raising the alarm after Tina and Watson split.
So the defense will need to push Dr. Stutz into testifying that there could have been a moment in this timeframe where Watson could have lost and replaced his mask that he did not see. Watson's statement was that as soon as he adjusted his mask back on, Tina was sinking.
"WATSON: ..her hand hit my mask um it knocked my mask sideways so ah I had to, had to let go ah let go and kind of turn back so that I would have some you know that I would have some space
cause at that point I didn’t have a mask"
"WATSON: my mask cleared turned back around and at this point she was going down um, I don’t know if ah if she was still kicking or not ah but she was looking up had both her arms out you know reached, stretched up almost like looking at me reaching her arms up to grab.. "
