One Direction - Twitter questions - TMH Tour (23/2/13)

This is the part in the show where the boys take time to answer some of our twitter questions whilst being their usual remarkably quirky selves. Attention: A lot of hugging seemed to take place. Questions: Can you mime an animal and the audience has to guess which one? If you could go back in time, what would you do again? Say your favourite line from the Harry Potter movie?
