Dobby is a complicated character. Quote:
I’ve just got one question, Dobby,’ said Harry, as Dobby pulled on Harry’s sock with shaking hands. ‘You told me all this had nothing to do with He Who Must Not Be Named, remember? Well –’
‘It was a clue, sir,’ said Dobby, his eyes widening, as though this was obvious. ‘Dobby was giving you a clue. The Dark Lord, before he changed his name, could be freely named, you see?’
I imagine I haven't understood what he wanted to say.
If Voldemort (Tom Riddle) could be named freely, why he didn't say his former name the first time? Though, he is saying he had given him a clue? Without saying the name?
