Lost Episode Titles?

We're trying to stay spoiler-free over here at The Top Pop Stop, but some things are too good to pass up. DarkUFO, whose info is usually pretty reliable, has posted episode titles for the first seven of 18 episodes.

Just to be safe, take it with a grain of salt, and those who want to remain totally unspoiled should abstain from reading these titles.

1. LA X
2. LA X (two-part episode; note the space between LA and X!)
3. What Kate Does
4. The Substitute
5. Lighthouse
6. Sundown
7. Dr. Linus
