I just watched this episode last night. I must say that it's probably my favorite of season five so far. It is definitely my favorite Odo episode so far too. It was really cool to see this side of Odo. He seemed sooo human in this one. I loved it when he was celebrating, pouring drinks and talking to Quark about how the baby changeling had changed his life/perspective. It was just cool to see Odo so giddy about something. I also really loved the dynamic between Odo and Dr. Mora in this one. It was fascinating when Odo realized that his techniques weren't going to yield results so he finally accepts Dr. Mora's input, and they start seeing results immediately. Odo finally begins to understand that Dr. Mora wasn't trying to torture him. He was just helping him realize his potential. This seemed to signify a huge shift in dynamic between these two, and also have a large impact on Odo's interpretation of Dr. Mora and his motives. Great stuff. Their relationship is a prime example of why I love this show. There are complexities and layers to relationships between characters that goes much deeper than any other Trek series. It was great to get some more back story/details about Odo/Dr. Mora. I hope to see more of them together. At the risk of sounding like a wuss, I almost got a little choked up at the end when Odo finally thanked Dr. Mora. Really great writing in this episode. Oh, and of course there's the big twist at the end that I was glad to see happen. All around, a great episode that in my mind embodies what is right about DS9.
