He seems more 6 than 5 to me because he's always been portrayed as frenetically running after every thing that happens to him. As if he can't ever quite catch up. It takes him a very long time to take the reigns of his own life in his hands. Which is opposite from type 5, who does everything in their power to make sure they don't leave anything to chance.
As for his fixes, I agree with 3w2. I suspect he might have a 9w1 fix over 1w9, mostly because, even though he definitely cares about holding up to his personal morals, he seems to lack the resentment and judgement of other people's actions. But I could see a case for either.
Also, the writers write with the 'every-man' in mind, which would line up nicely with the 369 tritype, but that in itself isn't exactly an argument for it, ofc.
