I was inspired by the Malcolm in the Middle/Breaking Bad theory.
In The Wonder Years, Kevin Arnold’s adult narration is voiced by Daniel Stern, the same actor who plays a bumbling crook in Home Alone. Let’s see if I can shove these together.
After high school Kevin Arnold was drafted for the Vietnam War. While in combat he saw high school buddy Jeff Billings (the best friend after the falling out with Paul Pfeiffer) impaled on a makeshift bamboo trap. Kevin comforted his dying friend by telling him the Jets were going to go all the way. When they got back they would both go see Joe Namath win the Super Bowl. Jeff died in his arms.
Upon returning home Kevin suffered from severe PTSD which went unrecognized and untreated. Kevin was ultimately kicked out of his parent’s house by Jack Arnold who thought Kevin was just lazy. This led to a series of unfortunate events. Unable to hold any steady work Kevin turned to crime. Not wanting to tarnish the Arnold family name he started using the alias “Marv Merchants” (another soldier in his platoon that died in battle).
As Marv he eventually wound up meeting Harry Lime. Their partnership of crime was ultimately thwarted by the actions of 9-year old Kevin McCallister. Marv and Harry received 20 year sentences in prison. Unable to seek treatment for his PTSD and depression Marv wasn’t able to assimilate with other prisoners and routinely engaged in physical altercations. One instance led to a death. Marv was sentenced to life for murder. Because of his emotional outbursts Marv was often held in solitary confinement. The isolation proved to be too much. Rocking on his cell floor he would mentally flash back and narrate out loud his fondest memories, The Wonder Years.
