Heck, the show wanted them married, no matter what, and of course, there had to be someone rushing in to "stop the presses". A while back it was Chad, then Ben, now Claire. No wonder viewers get so nostalgic for a "real wedding". (and it is coming up with Brady & Eve as well,) Boo, Hiss on these non-weddings.
Claire could have told Gramma Hope any time before the nuptials were to begin, but instead she has to rush in, all breathless, determined to beat Ciara. So now, what? And yes, don't know why Stefan is withholding what happened with Abby. Maybe he thinks Chad won't believe him, or maybe he is just enjoying knowing something the loving husband doesn't know????
