I took my class years ago, so I don't know if it was required then... but no, I didn't have one and neither did Sotis.
All rEvo rebreathers from the very start have been provided with them.

From what I read it went like this: They had one diver with major problems and another who signaled he was OK. So they ran to get the diver with issues back on the boat, and then once the emergency was under control looked for the diver who signaled he was OK.I don't understand what happened to either divers because RB diving is way above my diving experience. But what I really don't understand is where were the eyes on the water, even when a diver gives the deck an OK they're not OK until their feet on onboard period........get it.....

You may very well need 2, 3 or more people to get a fully equipped tech diver out of the water and up the ladder if he's passive or unconscious. On a typical dive boat this doesn't leave anyone not directly involved in this.
One unverified report had three other divers other than Rob (diver #1). It appears factual that Mr Sotis (diver #2) was one of the possible three. His wife, Dr Sotis (diver #3) , may have been on the boat and there may have been another male (diver #4) besides the boat captain.
There is a little bit more information in the interview with Rob's parents here Rob Stewart, Toronto ‘Sharkwater’ filmmaker and conservationist, missing off Florida coast
It would be helpful to know how many people were on the boat when Rob was on the surface.
In the interview with Rob's parents I posted earlier, Rob's father says a fourth person on the boat was a friend of Rob's he brought from California (2:02-2:20 on the video).
Returning to the accident discussion. Assuming that both divers came up using the same gases and they were going to be low on oxygen at the surface, it seems possible to me that the instructor knew that he had only a brief time before an issue would hit him at the surface but that the recent student did not. Could explain Rob signaling ok because he did not know that trouble he was in.
If the victim stayed on the loop.... well..... The "dead bug" as we call it (dropping the DSV and losing buoyancy and sinking immediately) would be a real possibility.
