Interesting they had a call back to The Last Ship novel (which aside from the ship's name has no similarity to the show) when explaining the origin of the name Nathan James. So, are all the brass traveling aboard the Nathan James? Seems odd, with a carrier traveling right behind them you'd think they'd be there. Though, I guess this is one of those TV things where we just have to accept all the characters with speaking roles will congregate where the sets have been built. I had the exact same thought. I can see this happening. Slattery goes aboard the carrier, with a newly promoted to full Captain Kara Green as his flag captain. Master Chief, that one from the Kenyan military, and the Asian TAO.
