It was SOOO cute. He was going to chose Frankie because he thought that he only was in love with the Carol from back in Highschool. He went to go tell her that he chose Frankie, but couldn't find her. Everywhere he went (her school, a bar, etc....) he saw flashbacks of all the times they've been together in the past 3 years and realized that he was in love with Carol NOW, not just from years ago.
So then he finds her in a park and tells her this story. He even said how he was going to pick Frankie. Poor Carol. BUT then he explained how he was in love with her now and it was SOOOOOOO wonderful. She kissed him, they kept kissing, and then fireworks went off behind some buildings near them because StuckeyBowl was having it's 75th Anniversary Party.
Worth cathing in a rerun if they show it.
