It was Fred's death which was most heart breaking because he died at a most unexpected moment.Besides, Fred, like poor Hedwig was there throughout the serial from book 1 to 7.He & George were the best double act ever & given the fact that two of them were always together in whatever mischief they got up to one ,wonders what George would be without Fred.However,let's remeber that he died as he had lived..joking about everyone & everything around him.
Miss you Fred!
As for Dobby dying,I didn't feel too sad until I read the part where Harry dug the elf's grave by himself & then inscribed the words "Here lies Dobby a free Elf" on its grave stone.It was that poignant inscription that I found really heart breaking & which made Dobby's death really sink in.RIP Dobby!
As for poor Hedwig,I felt like most readers that it was an unnecessary death.(Maybe it was to spare Harry the trouble of having carry around his cage) 😭 Anyway,poor,reliable,beautiful Hedwig...
