After robbing an old man in an RV, he commits crimes much worse to evade capture. He kidnaps three different individuals, and steals two vehicles. That seems like a lot of work -- and a lot of extra time in jail --- over a wallet that couldn’t have had much money in it.
In other words, in order to evade the authorities for one crime, Ron commits much, much worse crimes. It makes no sense whatsoever. At the end of the episode, Ron says he just “needed money,” but if that were the case, why wouldn’t he have surrendered earlier, instead of gravely compounding his guilt?
And at the end of the episode, Mentor says he learned the lesson of the week too: “Don’t skip lunch.”
This is just…strange.
Maybe that knock on the head by Ron really did poor Mentor some damage…
