I thought you did a very wonderful job. You kept Harlan and Catalina as themselves but more grown up and obviously through experiences. I really liked how you handled their conversation and the whole thing of Catalina coming back.
Harlan's response to Cat's outburst was perfect.
And I love how she kissed him on the cheek and then he finished it. That whole part was so sweet.
Wonderful! I grew up with this show, and the first season was by far my favorite. I loved watching Harlan and Catalina together then, and I loved reading about them together in your story now! A lovely fic.
