Padma pretend to be her twin so she can have sex with boys and apparently girls? Somehow this does not seem to fit, for me, with her image as a studious Ravenclaw, which is of course why she does it. Her fellow students judge her, like I have, based on her house,which has had a negative effect on her social life. While her actions may give her some joy, it has to have some negative effect on her sister's reputation with the school, which is not really fair to Parvati. The crush on Hermione is an interesting tough and I am curious as to were you take it.
