It's nice to see that other people are trying to fight for a place in Severus' life, like Harry. (he's an equal opportunist with grudges). Maybe once he feels secure with Harry he can branch out and give other people the chance to win back his friendship/trust. I am a fan of Minerva-friendship.

and I'm not sure where Rosmerta is basing her idea about Harry from. Not that she's wrong, but before Harry was focusing his entire being on Severus I can't see him going out and falling hopelessly in love with someone - who then turns around to stab him in the back. I don't think he's ever been this intent on another person before. It's too much to draw out, too much passion, if he fell like this at every turn. This is his all or nothing shot, he'll never love anyone the way he loves Severus.
