Lol, another awesome episode. Kotomi is almost as cute as Fuuko in her own absurd way. And what was the deal with Kyou talking with Tomoya about girls? Was she referering to Ryou or herself (I can't remember if Kyou gets good grades or not but I wouldn't be surprised at all if she had her own interest in him)? And of course overly dramatic cameos from the best anime parent duo ever.
I really like how they find ways to incorporate so many previously established characters into each episode fairly seamlessly. Even though Tomoyo, the Fujibayashi's and even the Dorm Leader aren't seemingly involved with the plot at all they don't let us forget that they exist and keep dropping little hints about them so if the plot moves to them it won't feel strange at all. Good storytelling IMO.
