Original Commentary

Sofia doesn't strike me as the logical type... or the patient type... or the type that would pass up on a good argument. Not a good combination for poor old Dr. Paul, it seems. -Isabel

Modern Commentary
Dr. Paul is probably ten or fifteen years older than Sofia. They're at different stages of their life. They really aren't romantically compatible.

As I've said a few times, if Joy were dating Dr. Paul and Sofia were dating Dr. Fitzgerald, it would've worked out better for everybody involved- Terrence
