Don Lothario is a Sim in my version of Pleasantview. He is the son of Nicolo and Adriana Lothario, both of whom are deceased.
Don is the infamous town Casanova, womanizer, and promiscuous freak. He is in love with a grand total of 4 women, formerly 5, the fifth being Bella Goth, who was abducted the day after the Caliente sisters moved in. He appears to love Kaylynn the most because he did public WooHoo with her, but Kaylynn is also romantically involved with Daniel Pleasant, who is cheating his wife, Mary-Sue.
Don is engaged to Cassandra Goth against his will, as he is a Romance Sim and fears long-term commitments like marriage. Don's affairs may put him in the wrong place, at the wrong time, and his path will take him to just the wrong events.
