I can see similarities between Bae & Neal in that both are well traveled and have seen many adventures (aka Magic Trip). Rumple is looking for his lost son whereas Neal was always looking for his lost father. Both abandoned their families.
If in fact MRJ turns out to be Bae, I’ll find it disturbing that they used Neal Cassady as Bae’s pseudonym. Cassady was no hero and I’d hate to see the two associated. In my mind, Bae represents goodness & innocence whereas Neal represents immorality and corruption.
