Kate said this when she went back into her cage. What is the significance and anyone recently rewatched this one to see if there is parallels?

I thought she was repeating what she said in Man of Science, Man of Faith.

In White Rabbit, Jack established "...every man for himself is not gonna work. If we can't live together...we're gonna die alone".

Sawyer had been telling Kate all episode "it's every man for himself." But Kate finally understands differently. IMO, she loves Sawyer, and she wasn't about to abandon him. So she willingly climbed back into her cage, and angrily threw the 2nd half of Jack's monologue back in Sawyer's face. Kate gets it, and she's not running any more; Sawyer still has to learn to act on that way of thinking, and acknowledge that he needs her.
