At around 9.00 minutes in the video part 3. Jung states:

He is most certaintly thinking.
Is Intuitive.
Has difficulty with feeling
And his relation to reality is not that particularly brilliant.

On this basis someone stated that he is introverted thinking with extraverted Inuition.

This would line him up as an INTP.

I would agree with this. He isn't decisive enough to be an INTJ. He is absolutely an INT, just whether he is a J or P. And thats self evident if you are an INTJ (Because you know he is slightly different and everything is a bit more open).
