I think this three episode story arc is one of my favorites if not the most favorite one. It has just all the things I love about the show - hard decision, great dialog, stunning char moments, great story. I think the signs for this story to come were here all along and even if the last episode before it gave us the hint, I think we were not ready for something so big.
Somehow this has been falling on them for a long time and now they are in position when they have to act against Earth and I love how everyone take it. Sheridan leaving the ship, going closest to Earth he has been over long period of time.. and for what reason and how and meeting his old ship. I loved the anger Ivanova had and living it out on Marcus. Stunning
I really loved the writing on this episode. It was brilliant. To portray something like that, so lively, so deeply and movingly. They got the message trough.. and what kind of message. Loved the episode.
