Danny Pickett was one of The Others, and first appeared in "Three Minutes" in S2.



Pickett appeared to be an aide to Tom and Bea, and he played an administrative role as a quarry supervisor and may have been involved in Karl's punishment. He was Colleen's husband. After her death, he took out his anger on Sawyer and almost killed him. He was killed by Juliet in "Not in Portland".

Some good questions.
They played this character up a lot so I find it hard to believe we won't eventually learn something more about him or see him appear in a flashback.

Can you refresh my memory about AL's ex? I don't recall any of that. Did we ever see a picture?

I'm guessing he met Colleen, his wife, on the island or came with her to the island. Something about Sawyer's personality really got at Pickett and I'm not sure what set him off. Perhaps Sawyer conned him in another life??
