What would you say or do if your best friend didn't show up for your wedding and never even bothered to explain why? That's what happened to one viewer, Laura, whose close friend Disa was a no-show on her big day 17 years ago -- and Disa was in the wedding party. "She was a friend that I was really expecting to see there on that day and [I] was very disappointed, confused," Laura tells Rachael.

They ran into each other eight years later but avoided the subject and Disa continues to carry around huge regrets. "I really want to get this off my chest because obviously I haven't forgotten about it and I haven't forgiven myself for doing it," she says. "I really want her to know just how sorry I am."

Rachael has her buddy Justin arrange a reunion for this pair so they can clear the air. Watch the video above for the dramatic moment!
