Episode was really good, loved the bits with Robb. The soundtrack has been pretty awesome so far as well.
The events in the tent between Robb and Jeyne (ok thats not her name in the tv show...) have a pretty massive impact on the storyline, there was nothing wasteful about it. Disappointed about side-boob though, she was hot.
I watched again and realized that scene definitely had to be fleshed out and they emphasized about his Frey marriage and the bridge crossing, so yeah it was needed. I love side boob as much as the next guy, but definitely could have used much more tit scenery.
Not really a spoiler but just a difference from the book to the show regarding next episode

It's kind of hard to depict ships moving back with the current into a chain in a decent amount of time anyway.
