'Lost' star Evangeline Lilly has revealed her theory about her character Kate in the show.
Speaking to Entertainment Weekly, the actress said: "My personal theory on it... it's just mine - is that Kate has in her sole memory, actually gone through the three years that we've watched her do on the island and even her flash-forward stories."
"That all of that is in there somewhere - she just doesn't have a conscious memory of it."
"So what I'm doing is playing a woman who is constantly sort of in battle with herself."
"There are things within her that she knows and understands but she doesn't consciously recognise."
