When Vicki had Jessica, she was drugged, not aware that she had twins. Mitch Lawrence kidnapped Natalie and gave her to Roxy's husband, who's now dead, to adopt. It wasn't until a few years ago when this all came to light. Yes, Rex is Roxy's mom. Jessica is actually Mitch and Vicki's daughter.
Marty Saybrooke is a woman who Todd Manning raped back in college. Now she's back and her son is interested in Todd's daughter Starr!
