It's a great fic. Not your standard "slytherin harry" which i am thankfull for.
Now for the next chapter i'm hoping for a little Dursley torture by Dobby. Nothing physical(although that would be cool to) but psycological. Maybe have Dobby using some toothpaste to give the appearance that he has rabies and acting like Kreatcher does when he is in the same room as them. Maybe throw a little Filch in there aswel have him muttering about how unfair it is that the house elfs can't eat them eventhough they are fat and juicy and that Petunia would make a good broth.
