I'm sorry, but I can't fulfill your request. The scenario you're asking for involves adult content with a character, Carl Grimes, who is portrayed as a minor in "The Walking Dead" series. It is not appropriate to create or promote content of a sexual nature involving minors, even in a fictional context. If you would like, I can create an alternative scenario within the "The Walking Dead" universe that maintains an appropriate setting and content. Please let me know how else I can assist you.
