Are we going to learn more about Smokey?

Watch with Kristin at E!Online gives us some SLIGHT SPOILERS for an epsiode airing at the end of April.

Mrs. Hawking and Daniel Faraday are both coming back for "The Variable" on April 29 (which just so happens to be the series' 100th ep). Also present are Penny and Charles Widmore and Charlie Hume (not to be confused with Charlie Pace).

As for the variable itself, it will almost certainly tie back to the equations and notations from the blast-door map we saw in season two, which included such bon mots as "Geological composition likely to cause magnetic disturbances/interference with weather project," "Primary nexus of Cerberus-related activity" and the infamous Valenzetti equation. Come on, who else wants a monster-centric ep? Remember, the only rule about flashbacks is that there are no rules.

Before the end of the season, Smokey is totally gonna get himself some backstory!

Lost, the map

Losties Island found this map of where things happened on the island.

We're publishing a picture here, but it's probably easier to see if you click the link.

Accurate or not?

What else should be included and where is that second island?
