I read this too, and it seems kinda odd, because it is not like she was a regular character.
season 1 she was in five episodes
season 2 she was in three episodes
season 3 she was in seven episodes
It is really only with the current season that she was becoming more of a regular cast member.
And at least with the first two season I wouldn't think that it would have been necessary for her to move and live on Hawaii. Especially because the few episodes she was in where spaced out with several more that she was not in, which would leave a lot of extra time for her to do what she wanted too.
anyways....... I hope this doesn't mean that we are going to miss out on seeing her flashback and how she got to the island and stuff.
