1. Do Over Fic. I believe that it is gen. Harry returns during the Christmas holidays of his first year. He is under the invisibility cloak in front of the Mirror of Erised. He finds Snape there and realizes that Snape is seeing what life would have been like if Lily had chose him instead of James.

2. This one I believe is Harry/Voldie. Snape uses a potion in a potion in class that shows if one is pureblood, half blood or muggle born. Of course, the trio is used to demonstrate the potion. The potion shows Harry is a pureblood. A second potion by a different potion master shows the same result. Umfrog demands that the news that Harry is a pureblood be suppressed. That's the last I read

Thanks.
