This was great I loved what Gabrielle said and did to keep the Dursley's in line.
I will say I did not like Harry using the words bloody brilliant its to crude and too much like Ron I think Harry would speak better or he should.
I am pleased thing are going well between Harry and Gabrielle the bonding with the owl was a good detail to have Harry seems to get on well with birds so might explain some of why he trusts Gabby or was able to bond with her so easily.
I am glad Harry has Remus to count on a bit but I think his talking to Albus will be pointless as the old man was happy to put Harry at risk in the tournament so it would not be a surprise if he planned to damage Harry's mind to force the Dark Lord into the open and break Harry's resolve so he would be easier to control and accept or seek death.
If the Headmaster had concerns about Remus I bet the old man would see him kill by Severus for the greater good.
I would really enjoy it if Snape was punished for what he has done to Harry.
I liked the information on Gabrielle's parents I look forward to the next chapter.
