He seems like a very level-headed young man and I think it would be easy to have a casual chat with him (unlike most of the other people in my list). I wouldn’t quiz him on the HP role, as I wouldn’t be confident enough that I’d be asking him anything new. Instead I’d ask him about his future plans and more importantly, what his favourite things to do right now are, whilst he’s still young and allowed to be a little reckless :)
