Hmm this was what I wrote on another forum:
My absolute fave that I can probably watch over and over again is episode 18. The names were kind of cheesy but it was just hilarious the way Kurogane reacted to the allias' that Fye made up for them in the Outo (like when he had to pull Mokono off his face and they drew him to look kind of like a dog) country. Haha and I liked his (Fye's) drawings. I absolutely loved the animation in this episode too, Fye playing darts, when Syaoran and Kurogane went off to look for the information booth. The sakura trees were just drawn beautifully. And I like the whole incident were Kurogane sneezes and says it's because Fye is talking about him which he was. Mokono's convo with Yuuko and Yuuko talking about white day and Kurogane. And of course Sakura fixing Syaoran's bow tie, oh and when Sakura tried to remember stuff about Syaoran. Yea I don't think there was a scene in the episode that I didn't like XD
My other picks would be:
ep10 -for the animation and character background/develope for Chun Hyang when she got to talk to her mother and discussion about hijutsu ... I like how the leaves appeared as the result of using Hijutsu and when she had to say good-bye to her mother it was just very emotional and nicely done.
ep12 -even though there wasn't a lot of action I liked the flashback/back story/memories of Sakura and Syaoran's childhood. How the grew up together and got to know one another and so forth. For some reason I could help but laugh when Sakura gave Syaoran a made up birthdate because he couldn't remember/doesn't know which day was his real birthday. I really enjoyed the scene were Sakura showed Syaoran the birds and she's just so adorable when she was happy that she got Syaoran to smile. Also when they went back to the same place and she said there wasn't much for her to do yet but that she wanted to give it her all.
ep20 -mostly because of the scene where Sakura's sang in the cafe and the latter of the episode when 1&O first played as bg music. But I also like the animation when Syaoran trained with Kurogane for the first time, loved the how vibrant the colors were. Bee Train did not disappoint animation wise in this episode. And the very end of the ep were Syaoran comes home exhuasted and a bit scratched up from the training and Fye tells Sakura to take the first aid box to tend to Syaoran and later Fye and Kurogane find both Sakura and Syaoran fast asleep, too cute.
