Star Trek has, historically, been really really terrible with consequences.
On the original series, Kirk was present for the deaths of several important people to him: his best friend, his brother and sister-in-law, and two of the great loves of his life, one of whom was pregnant with his child. Yet he was never seen to feel any trauma beyond the episodes where those things happened.
And it wasn’t much better in the first wave of spinoffs. But if the trend toward serialization has given us nothing else, it’s given us TV writers who are willing to examine long-term consequences.
