Like was mentioned above, we're not really back where we started at all. Stannis is routed, and will need to do some serious regrouping, because you know he's too serious to give up. Joffrey has just lost a ton of street cred, and with Tywin in town, I imagine not only Tyrion but Cersei as well are going to lose a lot of influence. Winterfell and Jon Snow have been taken. The Hound, Sansa and Arya have come along as characters. I mean sure, big picture, the same sides are still fighting in the war, but plenty has changed this season.
And I'm stupid for thinking that was Lancel who came in before Tywin did.
