There’s plenty for Marie not to like Sebastian Ray-Defeo. At first, he humiliated and insulted her in front of strangers (though she tried not to remember it—he claimed that doing so was a “favor” to her). And now, even if only indirectly, Ray-Defeo is to blame for the fact that her twin brother could end up in a wheelchair. So why not ruin his mood—if not by sabotaging the wedding altogether, then at least by darkening his day?
