I don't like riddles myself, but to be fair, it was MK that made the "5" statement.
Which still makes zero sense to me, even with the "trees" hint.
5 types of trees?
Who signed for the 5 trees?
Location the 5 trees were delivered?
Something else quite damning on the 5 trees invoice?
He (MK) specifically says to think about the old Bruce Lee films and think about the 5 fingers and how important they are. I guess that means something to someone, but it's over my head. I recall these conversations during/after AM's search and it never really went anywhere.
Then he says "five real strong reasons, to keep thinking about number five and hoping for number five". Hoping for number five?
Maybe we need
@ProfilingEvil to pop in and clear this up, eh?
