Looks like it, there secondary characters but were major in S3.
Now for the bridge crew? nope. been there for 3 years and I don't remember there names. Some love for the Helm/Navagator but the rest.. Nope. Is it to much to ask for a B plot for the comunications officer? Or Tactical? Sheesh. Worse than Uhura, Sulu on TOS.
How long did it take for Sulu and Uhura to officially get first names? I don't recall any Sulu or Uhura based episodes, or movies.
They're not making 26 episode series anymore. That would be good or bad, but it does mean that there isn't room to really make an episode dedicated to Owo, Bryce, Detmer etc. They gave Airyam some time but it was just a blatantly telegraphed punch to make you feel sad when they killed her off in the same episode.
Considering they have had episodes dedicated to a lot of recurring cast, I think they've gone about as well as they could, and they've done a good job of letting you know the bridge crew about as well as you'd know a co-worker you don't socialize with but pass in the hallway on a daily basis.
