All sorts of memes are telling Shinji that his future doesn't look good.
In order to avoid becoming a Shinji in the future, or being kicked to death on the roadside like a roadside creature, Shinji decides to escape from Eastwood and never come back.
But fate had other plans!
At this critical moment, his cheat code came to the rescue; he managed to lick the package of an counterpart from another world.
