Voldemort didn’t just hide his horcruxes in different places, but also in different times. Of course, Harry follows. One horcrux landed in 1976.
Harry has a dialog with a voice... which is probably in his head... I don't really know, you read it and then tell me, okay? ONE - SHOT
My sister once said "Nooo! What kinda 'I'm-trying-to-survive-the-second worldwar-basement' is this" Imagine that you were locked up in a cell like that. With your least favourite person. Constructive criticism is allways welcome.
