In a recent interview with tv-guide, Thomas Dekker talked
about some of the transformations that his character will undergo in
the first episode of the season. As he described it, there's a lot more
bound up in the statement "confront the reality of his destiny alone"
than you might think. He said that John of Season two will almost be a
different character from season one. He will be colder and somewhat of
a jerk, as he hardens himself for what is to come.
