Is it though? We've been awake you a few days, maybe a week. Last we knew, Blue Steel was at the Antarctic, circa 200 years ago, then all of the Fog shut down and went dormant. Worst case is assuming All of Blue Steel is awake and on the move to...somewhere. Things is, they'd be going at a convoy speed aka as fast as the slowest ship. As a sub traveling by ourselves at max speed, we would be able to catch them, provided we could find out where they're going. And if all of Blue Steel isn't awake, I consider it fully impossible that they would just leave their sisters to whatever random mercy. So we should be good on both of those counts.
But is that even what you meant? I might have gotten ahead of myself in assuming I knew what you were talking about.
