Both you and your buddy must hang together as one on this, as my experience was that even when I wanted to turn around, my daughter trusted the dive guide more than me! I fought against leaving her below, even as the dive guide was telling me to surface alone! Yep, there are more weird experiences than can be counted!
Also, if the dive guide has the flag, and you have not got your own "safety sausage" DSMB, the boat will find the DM and not you, which could also happen if you get separated by accident.
You and your buddy, not the dive guide, are responsible for the safety of both of you. That being said, you and your daughter need to have a serious conversation about the responsibilities of being a buddy, including ascending together, and insuring you both get back on the boat safely. There are countless examples of a diver being sent up by themselves only to have a major problem before getting on the boat. When I dive with my wife or grandson, they both fully understand that when one of us wants to thumb the dive or ascend for any reason, we go up together, and I don't give a damn about what the DM thinks or wants us to do. Both of you should have a deployable safety sausage and reel, and know how to use them. Leaving your safety in the hands of a DM or guide is a recipe for disaster.
