Christina had left her husband Stuart a few years ago because of his substance abuse problems. He tracked her down on the internet and came to visit her at Mode to tell her that he was dying of a rare disease. Christina didn't believe him at first, but soon realized that he was telling the truth. She agreed to be a birth surrogate for Wilhelmina in order to raise enough money for Stuart's medical treatments. Unfortunately, Stuart was told that the treatments were unsuccessful.
Eventually, when it was discovered that Will was his and Christina's son, they eventually left back to Scotland to raise their son. Portrayed by Derek Riddell.
