You mean away from being the Rainmaker?
I haven't seen it since theaters I didn't get that sense at all. What makes you say that?
Wasn't she a pleasure chick like the other woman?
There are a ton of misdirections by Johnson in the movie with this character, and the time travel logic is pretty shoddy...so its tough to explain what I'm getting at or giving any real theories as to what in the hell is going on, because I fear Johnson would just give the same old shitty answers he did in a few articles when the movie came out...which was basically "its a movie about time travel, stop making it more complicated than it is"...
Cid is to the point certain Sara is not his mom, but, then again, perhaps she really is not the mom he knows and Sara's story is legit, it seems pretty strange that they make it a point for Cid to be certain Sara isn't his mom and Sara's story is pretty vague...the only link to Sara legitimately being Cid's mom is the fact that Sara was a Telekinetic and Cid becomes a super villainous super Telekinetic.
Cid becomes the Rainmaker because of what happens in the field...in the loop that he becomes the Rainmaker...Old Joe kills Sara and scars Cid (remember when Sara says "things become easily infected on the farm)...that non-fatal wound becomes the reason The Rainmaker has a fake jaw and his transformation from little kid to villain starts when he runs away into the field.
Sara "knows a little too much"...she knows of Loopers, but she also knows of what she has to do...she's pretty quick to the point when Young Joe learns Cid will become the Rainmaker and states that things will be different if she parents him. Also, the mob knows a little too much about the whereabouts of the children Old Joe is hunting down. Abe had a map on the wall of his office and they were able to track Old Joe and the fact that (I forget his name in the movie) Garret Dillahunt shows up at Cid's home.
A general theory (and honestly, its silly considering the director won't even have any kind of real answer to this)...Sara was looped back (much like Abe was) to raise Cid to guide him away from being The Rainmaker...perhaps Sara is another loop's version of Cid's mom...I have no idea...
Way too complicated and the film itself is full of holes (I enjoyed the movie a lot FWIW) in regards to the logic of time travel...but general idea is that the Sara character is super interesting to me.
It has a ton of Terminator like logic to it, and that path needs a lot of weed to hash though those paradoxes.
