Also, why should either of these be a sympathetic character?
Why should we care what happens to them?
Imagine a blackout occurs in the middle of the episode causing you to miss the rest, and it's 1988 so you can't get it On Demand or from a torrent site. Your next opportunity to see the rest is when it's rerun in a few months.
Would it be a big deal? Would you be antsy to see what happens to Jameson, or what happens to the hostages, or more exposition of the backstory?
The only characters we have any reason to care about are the regulars we already cared about before the episode, and they have nothing at stake here and don't do much in the episode. The Enterprise's mission is taxi service.
