I absolutely adored the way their relationship went from antagonistic to not wanting it to end.
The best bit though was when Harry, Hermione & Ron were discussing the situation *again* and Harry only had to look a certain way at Ron for him to know Harry didn't want to bond to be broken and that Ron seemed absolutely fine about it. This shows the level of trust and friendship between these two.
I also particularly liked the fact that Ginny wasn't bitter, like in most stories and I'm just as bad as everyone else doing this. I want to definitely try something where she actually encourages Harry to go to Snape, but that's for next year.
