This show is just full of friendships; it's something that we talk about on The Orb all the time. Every time we talk about one of the characters we are quickly talking about them and their relationships. I really love the characters and their interaction with each other. I have always had a personal soft spot for Nog and Jake as well
And that taps into what I feel is the neatest feature of my current re-watch of DS9. There was a lot going on in this series at any given time. So much so that no matter how attentive I thought I was being at the time there was simply just too much to take in and fully appreciate.
I would also add that it helps that I watched Deep Space Nine religously when it was in production so I know how things generally turn out, therefore, I can now look more to the nuances and the periphery rather the just focusing on the core.
