"Stranger in a Strange Land" Spoilers

The upcoming episode scheduled to air on February 21, 2007 is Jack-centric and entitled "Stranger in a Strange Land." The official ABC synopsis is as follows:

A power play ensues between Jack and "The Others" as Juliet's future hangs in the balance. Meanwhile, Kate, Sawyer and Karl continue on their journey away from "Alcatraz."

Jack's flashbacks will take place in Thailand, where he'll meet a girl and get a tattoo. In the present, Jack will meet Isabel, the mysterious Other who will read his "ironic" Chinese tattoo, as I've mentioned previously. Kate will ask someone (probably Karl) nonchalantly, "What did you do with the people that you took? The kids?" We'll also see the return of flight attendant Cindy in this episode, who now appears to be one of The Others. According to an ABC trailer, "The answers to three of LOST's biggest mysteries are finally revealed" in this episode.
