I'm late too, I'd try skip breathing while buddy breathing the old fashion way so I control the reg.
try to get both of us out from under the overhead and make a free ascent. DCS be damned.

The scenario is that there is not enough gas to get the divers out. Knowing that you are fairly certain you both cannot make it out, sticking together is a double-drowning death sentence. So, the question is would you accept that fate or try to save at least one diver - yourself?

There may not be any deco involved, but if there were, one of the wise dive planning strategies is to determine how much deco you are willing to blow-off to save a friend. Then, you try to plan dives that will never penalize you more than the amount of deco time you are willing to forfeit.
