Not sure what you are implying by using the term ‘fornication relationship’ but the few times that the Commissioner Reagan character was paired with a female, they were both single, consenting adults. Not strictly biblical of course, but no imaginary characters were hurt in the process.
That is the definition of a fornication relationship: two unmarried people having sex. Fictional characters are rarely hurt by fornication relationships. Real people often experience a wide variety of short-term and long-term negative outcomes.
