Rachel Blossom and Jughead Jones were childhood friends until Jughead had to move to Toledo with his mom and sister one day in middle school. Before Jughead moved, the two always hung out with Archie Andrews and Betty Cooper. They all hung out everyday, but of course Jughead was removed from the group when he moved. Archie, Betty, and Rachel remained friends, even though the Blossom family didn't accept it.
High school came along, and the Blossoms decided to throw Rachel out of the house because she was putting "a bad reputation on the family." She accepted it and moved in with the Cooper family, and bleached her hair so that she would look less like a red headed Blossom. She eventually dyed it an unnatural red because it was her favorite color.
Midway through senior year, Jughead moved back to Riverdale from Toledo and became part of the "Sad Breakfast Club" (as Cheryl would call it) again, and became friends with Rachel, Betty, and Archie again, and also became friends with Veronica Lodge and Kevin Keller.
