First time I watched it, I was like "eh... I feel let down", and then I watched it again and it was amazing!!!! Loved every minute of Nick and Monroe searching through the catacombs! By far one of the best episodes the show has produced!
I think you may need to look those up yourself outside the wiki. I understand that sometimes the admins post up such content pertaining to the upcoming episode but if they haven't done this as yet, then you may need to look elsewhere.
