With Paige and Jack in the opening credits it's unlikely. I really hope they don't kill off anyone. If it's Lauren it would be tough on poor Brad - his son & dad dying and then his soul mate on top of that!
I don't think a 30 second tryst in the back of a boat shed would be called a soul mate .... he didn't even look for her after the event. Wasn't till Paige turned up and his marriage with Terese was turning sour (wanderlust returning) he started to roam again ...
