Having all the companions involved DAO style was something I was expecting when I entered the High Hall and I was scratching my head when I noticed they weren't there. I wanted to hear their thoughts on what was going on, get last minute advice, etc. It would have been cool if everyone had something to say when you give the speech. I doubt they have more important things to do at camp when the city is burning, and I don't want to have to headcanon what is going on with them - I want to see it and have a big epic battle with them fighting alongside me.
