Grindelwald has a personal vendetta against Theseus Scamander who has been a thorn in his side for years.
December 1927: Theseus receives a missive during an important meeting of british and american aurors that discusses Grindelwald's possible next movements. The only thing contained in the letter is a bloody lock of curly reddish brown hair.
Six months later Newt Scamander is officially declared dead.
June 1931: Percival Graves encounters a young no-maj artist in Paris who bears a striking semblance to his best friend's little brother. The young man doesn't recognise him at all.
