Well, hello there! How fascinating, visitors! You may be wondering just who I am - and it may come as a shock. You may know my son, Jack Frost. He has become quite famous, hasn't he? Did you know he has a sister, Emma? And don't forget about his mother! No no, can't forget her. I also have another daughter named Jenny - quite the soldier. Oh, where was I? Ah, yes. I'm the Doctor. Also called William, or Will, Frost, and John Smith but mostly the first two. Pleasure to meet you. Care to come on an adventure, or two?
