and don't feel like I learned much from it.

Except that the Guardians are the ones who know what 52 is, and that it is some sort of guiding principle for them. 'Path' could easily be a figurative path as well - ie, the path to righteousness or whatever. I was amused by them using it as sort of a 'Let's Go' type cheer - like they should have all had their hands in the middle for the big pre-game rally. "52! 52! 52!" Or they should have been giving each other pounds. "Yo, 52." "52, dawg."

Not sure how Superboy Prime will figure into it.

There have been so many allusions at this point... I really hope the 'answer,' if there is one, isn't some kind of metaphysical bs when it comes.
