I don't see how either could not know about the 3rd, unless the 3rd is actually the original, who created Marc, and Marc created Stephen.
Stephen didn't know about Marc bc he was created by Marc, so maybe Jake created Marc.
I can't remember, is Marc ever referred to by name by his parents in the flashbacks?
