From what I remember:The whole first half was flashbacks, telling the story from the begining. No surprise there.
In the final "lessons", the men & women must share their world with their partner.
I missed what Mindi did for Richard.
Richard shared his love of the piano with Mindi (they got all dressed up & sat at a baby grand). Richard plays the piano with great talent. He and Mindi had a lot of fun...she said it would've been better if they'd had the piano the whole time. They'd have enjoyed eachother more. She accompanied him on a song he wrote for her. It's was funny. Something about "Mindi, It's so windy when you're not around," and it had some funny lines.
I kind of missed the part where Caitalin cooked with Chuck. I just caught their dinner. They had a nice coversation. Caitalin told Chuck she was so impressed with how much he has grown during the show.
The final four sat in the bedroom talking. They hugged eachother & went to get dressed for the elimination.
Richard started freaking out, not knowing what they'd be tested on. He was a wreck. Mindi just hung out and told him to calm down.
Chuck & Caitalin just sat in their room making occassional small talk. You could practically hear the crickets chirping.
They go to the final elimination. Chuck & Caitalin go first. They have to answer questions about eachother (WHO COULDN'T SEE THAT COMING FROM A MILE AWAY????). They got 8/10 questions right (how to spell Caitalin's name, Chuck's birthplace, his college, etc). Richard & Mindi were next. They bombed the first few questions & then worked to tie Chuck & Caitalin (birthplaces, travel questions, size pants, etc.).
I think the tiebreaker round went around twice or three times before Chuck & Caitalin won.
