That las scene where Castle is offering his hand to Beckett and she looks at it before looking at Bracken again and finally takes his hand made me remember Always, of the struggle she went trough when trying to choose between Castle and her mother’s murder and it shows how much she’s grown when she follows him without a doubt. That she doesn’t have to choose between the two anymore is prove of her commitment to move forward and yet she still has the ability to look into Johana related cases and not get consumed by it… I love her character development, she seems more complete now
I also don’t think that it is rewriting the Bracken mythology that Vulcan Simmons worked for bracken. He knew an awful lot about her mothers murder.
And even more so, Raglan. His knowledge during question fits right in with McAllister’s assertion that Simmons killed Raglan….
