I really liked Snape here, exceptionally brooding and moody. It was funny how Snape didn't realize and couldn't admit that he was attracted to Harry. You portrayed it so well. It was obvious that Snape was not used to romance and didn't know what to expect or how to respond. And I liked his insecurities, not willing to believe Harry's compliments and such. Your characterizations were great. The awkwardness was endearing. And I loved the mindplay, it was an interesting way to get them to reveal things to each other. Great job on this fic!
