I was lucky enough to meet the Amazing DanTDM at MineCon 2013 at Meet and Greet. I ask him for a interview and as it was getting late and nobody else was in the line (I was at the back), he agreed!
D=Dan
C=Me

C: Thank you for agreeing for this interview!
D: (Shrugs) Anything for a TeamTDM member.
C: First things first. How did you come up with the idea for Dr.Trayaurus?
D: He came up in my head as i was thinking for a name for a sciencist. (Not sure that's the spelling) I just put words together.
C: You first played Minecraft when your brother asked you to come round and play this new game. What was going through your mind as you first played it?
D: I loved it. It was seriously good fun.
C: And then you bought two accounts for you and Jemma. 
D: Yep. It was so good, I bought two accounts so we could play everyday.
C: And then you made your channel.
D: TheDiamondMinecart, the reason i'm here.
C: And what a great thing that is. 
D: Yep.
C: How bad were you as a newbie?
D: Not that bad. Some things looked weird, but i was quite good at the start.
C: Finally, do you have any advice for new minecrafters, like my sister.
D: Ha. Keep building. You'll soon get better at it.
C: Thank you, Dan.
D: That's Ok.
