It sounds terrible, but Fletcher wasn't really going anywhere. lol. Poor guy got the short end of the stick. But he went out heroically. Considering his past and all he felt guilty about, it's the way he would have wanted to go.
Oh, the "army" that was there isn't around anymore. They were on the CG ship which is gone now. The only army characters from there around are the ones that were claimed. Desmond will be gone soon, he was never going to be permanent. Was only brought in for character development.
Andromeda & Asda will be taking back seat. Morgan and Gaz will be the most active.
