Note: spoilers for S3.
Little Wellick Jr. has a hell of a Marty Stu backstory.
Like, he gets adopted via Social Services to some random family. In his late teens or 20s, he gets curious about his biological parents. And then uncovers who they were and why he wound up adopted. And probably attracts the attention of the people who changed the course of his life in his infancy and winds up on the run from them.
We’ve all seen this movie.
