a miscarriage - and the two part on good terms. Relationship with Whitney, 2004 - 2005 After breaking up with Theresa, Fox returns to pining for Whitney. Though Whitney shows signs of affection for Fox, she is still engaged to Chad. Their relationship quickly falls apart, however, when Alistair reveals that Chad's biological parents are Julian and Eve Russell, making Chad the half-brother to both Whitney and Fox. Whitney is horrified to learn that she has slept with her own brother, and she turns to Fox in her despair. Fox and Whitney eventually become a couple, and Fox is thrilled when Whitney tells him that she is expecting his child.
