[DarkCloud]

Indeed true.
As for the symbolism thing, i think that both Garnet and Zerlina have really good and different opinions on the whole eye patch thing with Beatrix, i myself think that: Yes blinded by corruption and Yes cant see btween right and rong, but another thing is that (this has already been basically said, thought i might mention it anyway) it also refers to the song: Loss of Me, because Beatrix is lost in her own pool of thoughts and conflicts. Eventually she finds herself but is reminded of her dark 'Lost period' whenever she looks in the mirror at the dark patch.

i hope i got a good point... sometimes i lose myself too...
