1x28 - The Melancholy of Haruhi Suzumiya

With winter setting in, Haruhi orders Kyon to pick up a heater. With him gone, she takes pictures of Mikuru in various costumes for the movie's DVD cover, Itsuki helps, and Yuki is left alone to read. When Kyon returns, he finds only Yuki in the club room and falls asleep waiting for the others. He is woken by Haruhi (the only other student who hasn't gone home) putting her cardigan on him to keep him warm. Haruhi is mortified at being caught, but Kyon is only interested in the fact that he also has Mikuru's cardigan. Haruhi is in a good mood as she and Kyon share an umbrella on the walk home through the rain.
