Like dude stannis mentioned, the season has been subtly building up to the idea that Bash is all smoke and mirrors, and that his wealth is more of an act than anything else. This episode started with a few more direct references to that. After Sam's camera was stolen last episode, Bash balks at the idea of having to replace it, saying that it would have to come out of Sam's salary. And then, during the setup for the first wrestling show, Bash cheaps out on a number of production items, like lighting and sound. He also puts Sam at commentary, and uses Cherry's husband Keith as referee. Finally it's revealed that Bash's mom foots the bill for GLOW, and has since cut him off due to him spending $600,000 on production. So, that came together nicely. To be honest, this is probably my favourite low-key storyline of the series. They built it up well over the course of a few episodes, and never spelled it out directly until the very end... like a good wrestling storyline.
The fact that Carmen's brothers are Brodus Clay and Carlito is one thing, but to have Carlito eating an apple in this episode was a whole other level of wrestling easter egg. He should have spit in the face of someone he found not to be cool.
This episode felt like a climax in many ways, with the first wrestling show, and prior to that, the first real montage of legitimate wrestling training. Episodes prior to this seemed to gloss over the actual wrestling training, focusing on simple holds and nothing else. But this episode had Ruth and Debbie legitimately work through an entire match sequence, and a finisher. It was a nice touch. Also, this episode finally brought (what seems like) a conclusion to Debbie and Mike's marriage... with the worst timing ever.
This was a pretty excellent episode. But they used Dare from the Transformers animated movie soundtrack during the training montage. That's going to end up being the highlight of the ****ing season.
