What are the most satisfying and impactful character arcs in Burn Notice, and how do they conclude the series?

Burn Notice is a popular TV series that aired from 2007 to 2013. The show tells the story of Michael Westen, a spy who has been blacklisted by the US government and is now trying to find out who burned him while taking on various jobs to make a living. Throughout the show, we see the development of several main characters, and their arcs conclude in the series finale.

One of the most satisfying character arcs in the show is that of Fiona Glenanne, Michael's ex-girlfriend and partner in crime. Throughout the series, we see Fiona struggle with her past and her relationship with Michael, but in the final season, she takes a more active role in the spy world and becomes a valuable asset to Michael and his team. Her arc concludes with her sacrificing herself to save Michael, which is a fitting end to her story.

Another impactful character arc is that of Sam Axe, Michael's best friend and former Navy SEAL. Sam struggles with alcoholism and PTSD throughout the show, but in the final season, he becomes more focused and helps Michael and his team take down their enemies. His arc concludes with him finally finding love and starting a new life.

The series itself concludes with Michael finally getting the answers he's been looking for about who burned him, and he and his team successfully taking down the people responsible. The final scene shows Michael and Fiona watching over a young boy, and it's left open-ended whether or not they decide to take him in and start a family.
