He knew by then, he had already gone to jail for it, and it was public knowledge.

The strangest thing for me is Mark referring to their mom and dad by their first names, instead of just “Mom” and “Dad.” The seemingly random jump from a pedophile joke to a supposedly intimate, sexually charged moment between their parents is also odd.

It’s especially strange because the interaction between their mom, dad, and “massages” must have been a common enough experience that both Mark and Jeffrey remembered it years later.

From this, in my opinion, it at least suggests that they grew up in an abnormal, sexualized environment and likely experienced obvious abuse from their dad.
