The human rope climbing scene was one of my favorites during this episode. I can't claim I'd have seen such scenes too many times, especially with such attention to details. But yes, Angel vs Yuri melee fight was also surprisingly entertaining. Yuri isn't the leader for nothing, for sure, based on this episode.

It's indeed a good question why they were so worried about Angel finding the guild. It doesn't seem like Anger can erase memories, which would be a huge worry, so it must be for the future like Bill suggested. If she found out what the guild is for, Angel might continuously search for the current guild location, forcing it to do nothing but relocate time after time, never having time for weapons manufacture.
