One of the things I love so much about this little cartoon is Jessica and Craig’s relationship.
Jessica has shown to be highly intelligent for a girl of about four or five, and has shown to have some repetitive behaviors that may or may not be associated with OCD.
She is very schedule-oriented and–like Craig–is detail-oriented when it comes to her activities.
Craig–understandably because he is a kid–can get frustrated with her behavior before recognizing that he is very similar., which he will immediately apologize for.
Because of this shared maturity, they are able to be loving and comfortable with one another in a way that is not often shown with siblings in media. Craig is very loving and protective towards her and listens to her innocent rantings while also comforting her when she’s stressed. Meanwhile, Jessica is supportive of Craig’s endeavors even if she doesn’t always understand them. (Sour Candy Trials)
