Those Andorians were crack troops and operatives beleaguered by desperation whose minds had gone to terrorism and hatred. I think the writers wanted us to see that specifically because they would one day be founding members of the Federation. That sort of behavior is seen by humans from Terra Prime in the same series just three years later. We all had a great deal to overcome before the Charter could be signed.
I think it's fair to say there's still a lot to overcome 95 years later, too, which is why we're seeing it with humanity and yeah, I bet we'll see it with the Andorians, too. I like this because reality has shown time and again that 95 years probably isn't going to change as much as we might like. I think back to, say, 1922, and I struggle to believe we'd all be singing kumbaya by now even if the Vulcans popped on by for a hello (not that hello, the friendlier hello) at some point in the interim.
I definitely think we'll see the Andorians at some point, probably this season. They've been name-dropped thrice. First, Georgiou mentioned a nearby colony whose safety would be jeopardized by the situation with the Klingons. Then, T'Kuvma called them filthy. Then, one of the prisoners on the transport shuttle called them scumbags. We're getting a picture here and I expect the writers want to give us some dirty, downtrodden but ultimately very sympathetic Andorians -- kind of like Enterprise ended up doing, except we start out unified with them this time but old tensions resurface somehow.
I don't know. Something along those lines, maybe. Maybe not. On paper it sounds pretty unimaginative, but I think Discovery has already earned the benefit of the doubt insofar as unimaginative-sounding material is concerned. I think they'd do it fairly well if it's done at the writing level of the most recent episode.
Speaking of Federation founding members, though, I'm actually really wondering if Burnham winds up going to Vulcan at some point this season. We've seen preview footage of her there fighting somebody, I think, haven't we? Could of course be a flashback, but it could also occur that she's temporarily ousted from the ship and goes there for a couple of episodes.
Just randomly theorizing at this point.
