Harry meets Cho Chang for the first time in book three, Harry Potter and the Prisoner of Azkaban. There's instant chemistry between them, which develops even more in book four.
Scared
Dan said filming the second movie was much spookier than the first, especially because of the spider scenes.
"It was really creepy actually because Aragog was really there," he said.
"But I think it was worse for Rupert than it was for me cos Rupert is actually scared of spiders."
'No idea'
It also looks like Dan made some new mates in the second film. He struck up a friendship with Hugh Mitchell, who plays Harry's number one fan, Colin Creevey.
"At first, he's really shy but then you get to know him and he's completely mad, he's really cool, I really like him," Dan said.
