B5 and DS9 were pretty much developed concurrently, and given the amount of time behind-the-scenes development takes to get things from concept to ground, there's very little chance there was any actual copying going on. There's been animosity between fans of both over this ever since, but it really was almost certainly a coincidence. Both series play out very differently from that starting premise, regardless, and I'm more than glad we have both. Sounds like you're early in season 2, then. All of the best stuff is ahead. I definitely recommend getting back to it when you're up to it, if you can stomach just a little more elvishness. And those are some super heckin' cute bug girls.
