That's cool, I like her the most out of the secondary characters. She's almost become a lead in the show and Kirkman's comments pretty much intensify that, for which I am totally behind. I'm not sure if it's because I've always been into the comics more (though my love for the TV show and its characters has slowly grown over time, especially for Carl), but I just don't feel a whole lot for anyone other than the two leads. Again, that's probably got a lot to do with my own comic-book-intense fandom.
Fluffy, even though it was a flashback (and in all actuality it was more of a recap...the black/white makes it seem further in the past than it was, it was fairly recent and could be considered 'this episode' in a timeline-fashion), we saw Aaron's partner (I forget his name now and again) with the group just kind of listening in. Other than that, we didn't see him in the current events. Then again we didn't see plenty of people in the premier. Which makes sense, I'm not sure why there were some people elsewhere (and friends that I watched it with) wondering where everyone was...it was one of the most dangerous and intense (actually...unarguably, THE most dangerous) missions they went on. They'd need to keep certain people safe and look after HQ. It's safe to say that Carl was looking after behbeh and the rest of the secondary people were looking after HQ.
I think many, if not most of the clueless fodder of Alexandria are gone and that's a pretty safe bet to include even the higher ups like Deanna. But someone a few of the secondary 'leads' have to go. It's a must at this point. Glenn is looking more and more like he's going to be the one as far as foreshadowing, screen-time goes. I mean, it's just been the premier thus far so it's tough to say but I wouldn't be surprised if we saw a lot more of him and then...kaput.
