She certainly recovered fast from a major "c" section. I realize that she kept shooting herself up with something in her thigh. However, that ended way too soon. And I suspect the stuff in the syringes was the white stuff that comes out of androids when they are injured, like Bishop in Aliens.
Well, we're going to have to disagree on this one. I don't think the evidence suggests it, I think it's very flimsy and based on conjecture.
But of course, we won't know until the next movie comes out (if there is one... which if money talks I guess is a distinct possibility).

but maybe it's a good time to talk about how movies convey information. I think Nico is the one who mentioned having an issue with Pinbacker in Sunshine, which could fit into a similar genre of "scifi horror".
I've been watchin Sunshine last night, and while the tone is similar to Prometheus, regardless of any confusion over Pinbacker that perhaps could have been resolved better, the entire movie is organized and written to create a consistent thru-line, explain what is happening without sounding pretentious, and also justify choices that occur later in the movie. This stands in marked contrast to Prometheus. EVERYTHING is telegraphed, similar to how Christopher Nolan typically approaches his own movies, there's usually not something out of the blue later in the film or in a sequel where the audience feels like they were cheated -- everything was legitimately explained within the body of the movie.
For example, the end of the movie demands that Capa get inside the spacesuit quickly and navigate to the end of the ship before the bomb launches. He has enough trouble as it is, but it's believable that he can pull this off because he was required to be in such a suit twice already. The first time he was in the suit, it was because Mace challenged him to fix the shield, as he considered it Capa's error that they were in the mess with the shield to begin with, although Capa was not the best choice to fix the shield. But the natural conflict between Mace and Capa when Capa took too long to transmit his messages home (resulting in Mace not getting to say goodbye to family) contributes to Mace's response here. In another sequence, Mace drops his wrench into the coolant fluid and snags it out immediately, but his hand is still frozen painfully and it hurts him; this sets up our expectations when later he must choose to dive into the coolant in order to fix the machinery so that the computer can be brought back online. Boyle is constantly setting this stuff up for us, so nothing is like, "Wait, really?" (This is why I typically like his movies.)
There are many natural chains of "cause/effect" that play out through the movie, where literally everything is legitimately telegraphed -- no one just pulls something out of the air, it's already been justified by earlier scenes in the movie.
The entire issue with Pinbacker is actually hit again and again earlier in the movie, especially with the fascinating that Searle and Kaneda have with the brightness of the sun and how they "lose themselves in it" -- it's almost a religious experience, it dwarfs them and results in their particular choices... Pinbacker is just a more extreme form of this weird metaspiritual encounter with the power of the sun and whether humans should be trying to prolong their existence in the face of such power and grandeur. (Capa finds a different, albeit still spiritual, answer to this, at the movie's end.) It's all foreshadowed, all you need to do is watch the movie.
So the movie interlocks solidly and beautiful, there aren't really many "lost threads" -- everything "makes sense" especially on repeated viewings.
Things like Elizabeth being an android based on silly name gimmicks and things we didn't see in the movie (as we saw her bleeding profusely when cut open, she has human memories, etc., all in complete contrast to all the android experiences we've seen in every movie, including David's in this one) would at best a dirty trick by the director and writers, rather like David Copperfield making the statue of liberty disappear on national tv by just having someone photoshop it out of the video recording.
