Oprah was broadcasting her show with a guest (lets name her Jamie.)
Climax
She then bringing in the topic of lost/missing loved ones (with the Jamie's permission, of course.), and also the fact that her guest, Jamie, here has also lost one.
Falling Action
Oprah dropped some hints here and there while she spoke, then introduced that she had someone she wanted Jamie to meet.
Resolution
Oprah then brought out the guest, and to their surprise, it was Jamie's long-separated mom.
Jamie thanks Oprah. Like a ton. A TON a ton.
Oprah told them how she arranged this and they had a good talk. A great talk, even.
