Stella asks Clay, after he confirms he's a SEAL, if he's a color or a number. There are 11 SEAL teams, most of which are Tier 2 Special Mission units, save for SEAL Teams 17 & 18, which are reserve units and are considered Tier 3, and are known by numbers i.e. SEAL Team One. The Navy's Tier 1 unit is the DEVGRU, formally known as SEAL Team 6, which within JSOC is known as Task Force Blue. So when she asked if he was a color or a number she was asking if he was a Tier 2 or Tier 1 operator.
The scene where Ellis is briefing the team that the GPS was turned off, and they had lost the Centarius. She states the area in which it was lost is size of the continental United States. The average boat cruises between 30 and 40 mph. It would take approximately 17 hours to fly from The East coast to that region, using in air refueling. Which would mean the max cruising distance the ship could traverse would be approximately 700 miles in any direction. The search area of the circle it could sail would be approximately 1.53 mil miles. The continental US covers approximately 3.8 mil miles. Which is more than twice what Ellis stated.
When Clay and Brian are talking at the 51 minute mark of the episode, Brian is looking at a website selling Fleshlights on his computer.
