This episode is fantastic in every way. There's so much to praise. Toby, Michael, the arrival of Holly, the proposal of a certain 2 people, it's all good stuff. A great ending to the best season of TV I've ever seen. Season 4 is something truly special, nearly every episode could be one of my favorites of the series. Unfortunately it starts to go a little downhill after this, but really, it would be a huge challenge to top this.
