This episode is one of the most important. In my opinion it sets the end from here. It doesn't look that way at first, a central story about Venus and pedophiles, ok. But when you see Gemma's face and you see reflects of the inevitable to come, you know.
It is the first time we see the club trying to take care of business (like they did few years ago) but this time, they're so rotten, so doomed, everything falls apart and smell like the end...
