Questions Raised by "The Curse of the Black Spot"

WARNING: The following post may contain spoilers for the Doctor Who episode "The Curse of the Black Spot" (S06E03).
NOTE: For this post, I will refer to the "Siren" interdimensional alien doctor thing as the "emergency medical hologram".

1. Why did the emergency medical hologram take men who had mere nicks and cuts? They're not life-threatening, and what sort of triage system involves blasting people across the deck of a ship just to get the guy with a scratch?
2. For that matter, why couldn't the men who had been cut be released? The emergency medical hologram can figure out that some humans in our dimension use paired rings to indicate marriage which, in some of our legal systems, authorizes the spouse to make medical decisions, but even after acquiring several DNA samples it can't figure out blood clotting?
3. Isn't Rory made of plastic? I wasn't sure, after season 5, whether the Rory that we were seeing was the plastic Roman or the regular human, what with time travel, paradoxes, the destruction and rebirth of our universe, the rewind, etc., but a certain conversation in "The Day of the Moon" basically told us that this Rory is the plastic one. That being said, would he even have DNA? I'm not sure on the details, but...
4. Isn't Rory made of plastic? That is, would he bleed if cut? Would a cut even be an issue? Moreover...
5. Isn't Rory made of plastic? Is drowning really an issue for him? Even if his lung cavities filled with water, does he really need the almost constant supply of oxygen that we do? Couldn't we just drain him and make him all better? I mean, at this point, does being one of those plastic people (whose proper Doctor Who title escapes me at the moment) do anything besides giving one eternal youth and making one functionally immortal?
6. And what sort of name is "Rory", anyway? This isn't specific to the episode, but it's apparently "Rory" and not "Roary", which just seems a bit silly to me. :P
