Love it in DS9 when the little cute B plot is added in between the craziest main story known to man, but I also love it when the B plot is just as important as the A plot, but without the angst, so no one cares.
Like when Kira was having the O’brians baby? That was pretty important, but it was made a B plot. This was probably because you can’t control when someone is going to have birth, so they were just fitting it in somewhere, but there’s other examples too.
What about Rom and Leeta finally getting together? Y’know the actually pretty big part of the later show was just a B plot, which is actually quite surprising to me as I went into DS9 knowing they were going to get together, but I suppose nobody really knew how big of a part they would play.
Overall, I just find it funny that there is so much variety in Star Trek B plot’s from “extremely important to the plot” to “just there for a few seconds to have a fun story in between” all the way down to “what was the point of this” and “whatever that writing thing was between Jake Sisko and the creepy energy woman”.
