From what I’ve seen from the fanfics, fanarts, and fan edits, I feel like a lot of people don’t realize that Voldemort is like +20 years older than Bellatrix, Snape, the Marauders, etc. I’ve seen a lot of fancast where they’re the same age and it bothers me. I know the movies didn’t help since they portrayed that generations as much older with their casting choices but Voldemort was older than McGonagall.
