So did I
It was such an interesting twist to find out that Marcel's efforts against the witches are actually Davina's plans. I had a feeling she wasn't just a tool, but I never guessed that it was her idea.
It was also interesting to see a sort of parallel between Marcel/Davina and Klaus/Marcel. He sees Davina as a kid in danger who fought back against those who would harm her and decided to rescue her the same way Klaus did with him. It's a really cool echo.
