Mark and Steph have a lot more in common and I think they could actually have some fun .... unlike straight laced Paige who seems to have a constant scowl on her face and is always scheming and interfering. Steph, like Mark (apart from his cleaning fetish) are both a lot more laid back and prepared to see the best in others . Marks paranoia with Paige (not trusting her) stems from her own behaviour and actions knowing it could affect his career.
