I'm sure those from the sub present at negotiations told the rest on the sub about the admiral shooting the White House rep damn fast. And that the order was given, again, to destroy them without a second thought. I know, the two subs coming after them should do that, but to hear that people in charge are giving the orders in front of them! That's gotta unify the crew.
Hopefully it does and they dont have too much interpersonal conflicts with the crew anymore.
