Just watched "Interface" where LaForge's mother disappears/dies (I guess it is never confirmed that she dies).
Occurred to me that almost every single cast member accross all the shows has at least 1 dead parent. Is it easier to write characters that way?
I remember I heard a writer once saying that when you have a properly fleshed-out character, it's a piece of cake to imagine the world that gave birth to that character, and then it becomes easy to give them parents that make sense. And when you see a character that doesn't have parents, especially when the story calls for them to appear and they conspicuously don't, it's a good indication that the writer took at least one shortcut somewhere.
If a writer makes a thin character, maybe it's hard for that writer to make parents for that character, so maybe creating just one parent is a major achievement, and then they give up and say the other parent is gone for whatever convenient reason.
For Trek, I think it makes sense for most of the characters to rarely bring up the subject of their parents, because they're mostly all adults, and soldiers on assignment.
I think Worf made the most immediate sense to have obviously dead parents, because he's an orphaned alien. But then his adopted parents are both still living, and I think they were a good fit for "a world that could've created a Worf", so I don't think Worf was a case of laziness.
Picard had two dead parents, but I think they hardly went there, it was just something that was in Picard's past, and they chose to focus on Picard's brother and their sense of family responsibility. I don't think that Picard was a lazy character either. (Until the movies, of course.)
Edit: So it
can be easier to write dead parents, and I've seen at least one person suggest that it can be
an indiaction of lazy writing, but that's by no means certain.
