>>1040300>>1040304Betty and Veronica's inexplicable attraction to Archie is an elaborate coverup for their secret lesbian love affair.
Evidence:
Archie is the perfect mark because he will play along (unlike Jughead, who overtly states a disinterest in girls, or Dillon, who would figure out the ruse, or Reggie, who is too aggressive and will try to force them into sex). Archie's total inability to make a choice allows them both to appear taken at the same time, without actually committing or having to touch a penis. Their pretense for flirting with Archie (and other boys) in front of each other is part of some twisted power game where each tries to make the other insane with jealousy. This results in passionate, angry sex and sweet, make-up cuddling.
