I think these scenes are new as I don't remember reading them before. I like the morality play here. This mission while arguably necessary falls well outside Starfleet ethical standards. Telling that the Romulan seems to struggle with this the most.
Oh and I like the tension you're building with the freighter captain having sold out our heroes who, seemingly unbeknownst to them are already heading for a trap.
Now I'm actually excited to find out what happens next even though I'm supposed to be familiar with this story already.
