flashback: Mr. Eko
Goof: In a flashback, when Mr. Ecko has his hands tied in the church, at about 29 minutes 10 seconds, he pulls the knife out of the the table twice. The first time he uses the knife to hit the main "bad guy". The second time it is pulled Mr. Ecko uses the knife to strike one of the supporting "bad guys".
Trivia: Final appearance of Adewale Akinnuoye-Agbaje as Mr. Eko in the series. Akinnuoye-Agbaje never made a guest appearance after his character's death, as most other main characters on the show did.
Title Meaning: The "cost of living" is an economic metric. Eko defends his actions as necessary for his life, and his defense then costs him his life at the monster's hands.
