Full disclosure, I've never liked the character of Doris McGarrett. A lot of information about her has just never made a lot of sense to me. This episode finally clears up most of the questions you will have had about her as a long time viewer. Personally, I came out of this episode liking her less than I did before. She spent so many years away from her family working for the CIA and when she "comes back from the dead", she then went away over and over again instead of staying in Hawaii and having a relationship with the children she had to abandon while working for "The Company". It's no wonder at all that Steve was always trying to make a family, first with the Navy and then with Five-0.
