It can't be me since I posted last.
It is slightly daunting because the next installment may well be the one that determines the dynamic between the characters. Suddenly you're having to think about what other individuals, besides the one that you created, would do in a given situation.
That said, it's only a writing exercise and you can't really mess it up. Somebody should just jump in and write something.
For the record I don't care what anyone does with Adrian Slawny, as long as you don't kill him. I have my own long term plans for the character, but I'll either adjust them or completely rethink them depending on where the story goes.
