In 1985, a young adult Marty McFly travels back to 1955 where he meets both George McFly and Lorraine Bates who would become his parents.
In fact, Lorraine Bates is very smitten with Marty.
Marty has many interactions with his future parents.
Returning back to 1985, wouldn't his parents recognize their son's voice and looks to be the same as that Marty who got them together in 1955 ?
Upon Lorraine doing the laundry in mid 1980s, wouldn't seeing her son's "Calvin Klein" underwear put 2 and 2 together?
