Okay, let me get this straight.
Josh Holloway isn't Sawyer. The letter he keeps reading was what he was going to give to the man that cheated with his mom, who was identified as "Mr. Sawyer". His mom was killed by his dad, then his dad committed suicide.
Then Holloway saw the same scenario later on in life and became "Sawyer"...the man who cheated with his mom.
That's some fucking storyline.
