In the Harry Potter film #2 ( The Chamber of Secrets ), there is a moment where Harry says :
" I think it's time to use my dad's old cloak again. "
( Sorry if I misquoted by a word or two )
We only see in film #1 ( The Philosopher's Stone ) that Harry gets the cloak as a Christmas gift, but it is not explained who gave it to him or whose it was before. So I wonder, where did Harry learn that this cloak belonged to his father and who presented it to him ?
