I feel like these hooded figures in mystery shows / movies always give me a "guy" vibe, even when the reveal turns out to be a female. I don't think too much about what the hooded figure looks like because it ultimately doesn't mean much in terms of clues about A, really.

And to be fair, you can't really distinguish features / body type (other than knowing they're not particularly overweight) from those sort of clothes, anyway. They've probably just got a stunt double who's generally a similar height to the actor who will be revealed as A.
