Oh my glob. I didn't even get to look at this all the way through... [ Unlike her, but she's also been busy at StarkTech. She does a quick skim. ]

And the shipyard might have info about where that sub is now, if they're even on it. 'Oxygen tanks,' 'not inconsistent with a submarine'... We'd have to be sure that they're in there before we can rescue anybody, but it's worth not ruling out.

[ Russia's still a big place. But if they are underwater, that makes a rescue mission that much harder. How do you evacuate all those people? Hijack the sub? Their options just got so much smaller. ]
