Lockdown

Halfway done, Lockdown is episode #41 of 82 and appropriately it centers around John Locke. The off island flashback shows how John is totally locked to the whims of his con man father. After attending the father’s funeral he is shocked when a few days later the “deceased” shows up requesting help. He needs Locke to go and retrieve the money he stole from a couple of very bad dudes by unlocking a safety deposit box. On island, John has to enlist the aide of suspected bad guy Henry Gale, who he has unlocked from his cell, when he gets stuck under a blast door that automatically closes as part of the titular Lockdown. While trapped under the door he gets a brief glimpse of a strange map.
