She is "playing" the same caretaker role in her real life as in her Other life. She took care of people on the plane as a flight attendent and now as a "mommy" figure.
It seems like she had a nice long session with that film that Carl was watching.
Good point about her role. I guess you can't really change who you are.
Cindy and the other Others were there to watch Jack in his cage, like an animal in a zoo. TPTB love Twilight Zone and I think this was an homage to People Are Alike Allover, an eppy where an astronaut is locked in a house as an exhibit for Martians to view (but he was unaware that this was to be his fate). The Others want to view him to see how a human reacts to being imprisoned, yet another experiment being enacted on our Losties.

Exactly I think she was taken and brainwashed and the rest of the people what were with Cindy were also taken from flight 815 - tailsection
