This was a beautiful episode, from the writing, the animation and the OST. We get to see Lavie, and by proxy also Claus's backstory, which is bittersweet. We already know what happened to their parents, but to see and feel what the characters are feeling is different than just telling it outright, which makes it feels more tragic. I like how Lavie and Claus stays by each other side, as I said, two side of the same coin. But what shock me was the news at right at the end of the episode, that shook even Lavie too.
