Dobby. It's the only death that no matter how many times I read the stories, makes me cry like a baby.
I was genuinely heartbroken, I hurt so bad when Dobby died. My heart was bruised and is still bruised.
After Dobby, it would be Fred Wesealy. I hate it, I hate it, I hate it..
Sirus was the one character in the book I never truly connected with and still fully don't to this day. He was also the only character in the book that I didn't cry for when he died. I liked him, but I didn't feel connected to him at all. And in my opinion, I feel like Lupin was more of a father figure for Harry than Sirus.
