Carpe Noctem. The way the singing, music and dance combine to tell the story of Alfred's dream is just fantastic. In addition, it really gives the ensemble chance to shine since none of the main characters are active participants.
Totale Finsternis - the love duet with the right mix of curiosity, lust, fear, giving oneself to the darkness despite it and maybe, just maybe, understanding and romance between the two participants. The portraits singing in the background and watching Sarah's entrance into the castle add to the atmosphere.
