Madeleine's speech to Michael basically telling him to appreciate his friends. So necessary! LARRY! Tim Matheson <3 <3 <3. The whole segment inside the British consulate I was just waiting for the "big moment" to happen and then wow, the twist at the end. So didn't see that coming although maybe I should as I think the show has played the "victim is actually the evil mastermind" card before.
The thing I love the most about the show is how it constantly reinvents itself. I mean you might wonder how a show about a burnt spy can constantly evolve but every finale is a game changer setting up a new scenario for the next season. Nicely played.
