Tonight's episode of Legacies sees The CW series not only go full musical production for "Salvatore: The Musical!" but in the process also pay tribute to the series that started it all, The Vampire Diaries. While the series has made a number of nods to both The Vampire Diaries and The Originals over the previous two seasons, tonight's episode is the most self-aware yet, with the students at the Salvatore School portraying the very people responsible for, well, their whole story. That means taking on fan-loved characters such as Damon Salvatore, Stefan Salvatore, and Elena Gilbert as well as revisiting beloved storylines. It's a big challenge, and according to Legacies star Caleb Lee, honoring The Vampire Diaries is something that was very important to not only him but everyone else involved in the episode as well.
