I always like the history episodes. 2x02 had Rose and Ten getting knighted, the whole Scottish accent thing, and the appearance of the famous "tiemtongue". 3x02 had Shakespeare being a h0r basically, lots of nerdy literature references that I loved, and Ten in one of those ruffly neck thingies at the end. While sadly he didn't toga up in this episode--Donna sort of did--I still loved it anyway and here's a little numbered list of reasons why.

1. Ten was looking delicious in this episode, especially when he got all sweaty. And when he shouted. And when he ran and jumped through windows. And even when he was sad about Gallifrey.
2. I liked Donna's period costume! Also she'll be properly-dressed next episode, so will we get to see lots more cool Donna fashion? I mean, how many bags did she pack?
3. HE SAID BARCELONA HDIBGHSIDGHEIOAEIOHWF;;;
4. I saw it coming (hurhur) but still liked how the house gods changed at the end.
5. I love the history episodes.
6. The woman who talks about the Ood in the next episode, the Indian woman, looks like my journalism professor Dr. Ghosh. Seriously.
7. By the Emma Theory of Doctor Who episodes, next episode should be my favorite of S4, but I doubt that'll happen because I think The Doctor's Daughter and the one when Rose returns (Midnight?) might be contenders for my favorite.
8. MOTHERFUCKIN' SQUIRT GUN. That is all.
