That ending with Nora's message in the Time Vault really tug at my heart strings. Well played writers of the Flash! It is interesting to see the similarities between Arrow and Flash this season. Both shows featured the main protagonist finding a new family member (sister for Oliver, daughter for Barry) who starts good, turns evil and then has a redemption arc in the end. Both shows, the new family member dies. And both shows, ended their finale on a real emotional note.
