In the episode "All's Well that Ends", the fifth season and the series "In Plain Sight" wrap it all up. U.S. Marshall Mary Shannon must contend with the protection of one last WITSEC person, a comely young model adjusting poorly to hiding out in New Mexico. Mary must also deal with the consequences of her long-missing criminal father's intrusion into her life. Finally, Mary must make serious plans for her own future with her baby as her office is threatened with closure. And, her long-time office partner Marshall needs to talks to her about something...
This is perhaps too much burden for one episode. The witsec issue gets resolved in the usual timeline. The issues created by Mary's father are untidy and their resolution is also less than tidy, even if there is a measure of redemption for both father and daughter. Mary comes to terms with her disfunctional family, after a fashion, and there are indications at the end that Mary intends to press on with her life as it is. There is an effort to wrap up the stories of the leading characters.
The least satisfying aspect of the episode, for this reviewer, was Mary's fateful conversation with longtime office partner and virtual soulmate Marshall. Previous episodes this season suggested both Marshal and Mary knew he wasn't entirely free to just ride off into the sunset with his fiancee, due to his attachment to Mary. This could have been a life-changing moment, but instead of champagne, we got warm diet soda and this long-time viewer was disappointed. But you have to see it and draw your own conclusions.
"All's Well that Ends" is highly recommended to fans of the series.
