Headscratchers / Star Trek: The Next Generation S6E15 "Birthright"

• Tokath threw away his career and founded the prison colony to prevent the Klingons from being executed. Is the prison colony still under the aegis of the Romulan Empire? If not, why does it still have armed and uniformed guards? If so, wouldn't Tokath get replaced by another Romulan overseer once he dies? And wouldn't that almost ensure that everyone still there, including the next generation of Klingons, would get massacred, since he was the only one who stopped that happening in the first place? You'd think that Tokath would be far from confident from the very beginning that his colony has any hope of lasting.
• Romulans and Vulcans are basically the same species, and have copper-based blood. Klingons have iron-based blood (or something very similar to iron, anyway). It would have taken major medical assistance for a Romulan and a Klingon to have a child together, most likely requiring the services of a dedicated maternity unit at a modern, fully-staffed/stocked/equipped hospital. There is no sign of any structure on the prison colony even vaguely resembling that level of sophistication, and it's a near certainty that there were no xeno-paediatricians captured at Khitomer or in Tokath's crew. So how, exactly, did Ba'el get conceived, let alone born?
  • As we see with Romulan and Klingon blood transfusions being possible, there's apparently more similarities than immediately apparent.
• Why doesn't anyone even consider offering Ba'el the opportunity to live in the Federation? You'd expect that Worf, who raised by humans and is a Starfleet officer, would have at least considered the possibility!
  • Her existence as a Klingon-Romulan hybrid would still need to be accounted for - the cover story that Worf creates for the youths who he does rescue is that they come from a Klingon ship that crashed. A Klingon-Romulan hybrid among the survivors puts the lie to that, as there's no particular reason that justifies her existence in that cover story. And the cover story is needed, since the youths are the children of survivors of the Khitomer massacre, with it stated outright that Klingon society would see them inherently dishonored for generations. And while one could assume that Picard and the Enterprise could keep that cover, Ba'el would also be unable to access either side of her heritage - like Ziyal in Deep Space Nine, she would be part of both cultures yet truly accepted by neither, especially since, again, her very existence puts the lie to the cover story and exposes herself and her peers to being dishonored and expelled from Klingon society.
