It looks like these two may hook up.
"Matthew sees Cain leaving the B&B and goes inside to find a devastated Sadie. He offers comfort and the pair share a kiss as it becomes apparent that there is a history between them. However, Sadie pulls away and asks Matthew to leave. Can Matthew offer more than a shoulder to cry on?"
I'm glad because it means Louise would be on her own and she will feel what it is like to be cheated on.
