Been watching an episode of Star Trek Deep Space Nine that I don't think I've ever really given enough credit to called "Times Orphan"
This is the best summary I can find. Yes it's from Wikipedia so if you're still interested scroll down and view the plot... it's a pretty deep story

@duglop Why do I love DS9? Because unlike with TNG, it came out of the gates roaring. There were no first-season jitters. And then when Worf joined, it became even better.
