Google says its pronounced "Fig", so Fig 20 in your pic. I can't find the abbreviation meaning. One common theme that comes up is "guided missile frigate".
Oh wow, I did not pick up on that but I think you are likely right. I liked that part, its something we haven't really seen in Halo before and it conveyed way more personality and emotion than all of Reach did IMO.
We asked about seeing the first episode early after we interviewed Daniel Cudmore about his part. I only saw the first episode exactly as you saw it, and I think it had only been finished with its edits that day.
Stewart Hendler replied to a tweet of mine though and said the Cadets helmets were actually from the ODST commercials. He agreed with me that they could have been better. Cool little bit of trivia.
