It was a nice story
It gave me a feeling of watching an episode with its major plot A and minor plot B construction. The characters felt quite spot on and in-character. Not many fanfic writer can do that really well
However, Odo's experience and how it happened (don't want to go into detail not to spoil to someone who first reads comments and then the story, but it should be obvious what I'm talking about) was a bit too humanoid for my taste. It could have happened completely different, not so... normal. After all, Odo is all but "normal but our, solid, standards.
Still, the emotional pack was great and I read the story with a great pleasure
