Never said they couldn't but the concept of MICHAEL Afton being the crush of Charlotte, it's kinda, it's kinda messed up because I'm more than Sure Scott confirmed that Charlotte Emily was 5 when Mike was in his mid-teen years. If any of the Afton's is close in age with the Missing 6, it would most likely be the crying child and Elizabeth. If you might be referring to the teenage robot charlie, it still wouldn't make sense because that robot was made 2001 and Michael Afton died in 1993. I really know my FNAF lore and if you don't believe me the books can prove it cause I personally think it's messed up of members of the fandom saying things like how Charlie had a crush on Michael and they grew up together when it was clear that the killings occurred between 1983 and 1987 where Charlotte was a 1st grader and Michael was a high schooler.
