That was one of the speculations. Another was potential issues related to raping Alice's mouth. I doubt either were the reason. More likely, all of the Ralphamale's antics were compounding, and he made the only rational decision to flee the country his daddeh have him and become an outlaw, gonzo journalist in Mehico.
Trying to think of all the factors that may have played a role:
- Car wreck stuff
- IP2 Alice stuff
- Ongoing Faith/Ralph 2 stuff
- Needed cheaper cost of living
- Easy Xanax
- alogs aloggin' him at his house
- debt collectors
- Bills related to the rental he and Pantsu left in shambles (This is assuming the landlord did a house visit when the lease was up for renewal and not after he fled)
I'm sure there's more, but that's all of the potential factors that come to mind that led to Ralph making the worst decision in his life.
