Question: Vampire (Spoilers)
Let me first say I've seen the film a bunch of times, I love the film but there's just one thing that never seems to make sense. So during the parade we come upon a couples making out, go down an alley and find a girl in a masquerade mask going at it with a guy in a cape and mask as well. They seem to be having a good time but then all the sudden you realize he's biting her and has fangs. She notices this and all of the blood and runs off, almost gets help but is shrugged off by Emma and her husband and then the vampire dude shows up again and kills her, leaving her in plain sight. This all seems really straight forward and if they had left it there it could have just been a good mystery but they didnt.
We realize during the werewolf scene that the vampire is Mr. Wilkins and here's where I'm confused. Why did he murder that girl and especially why did he do it by drinking her blood. This doesn't fit with his character as we know him so far and changes not only his M.O. but his victim range. I just dont understand the whole vampire part. Is he a vampire? Does he just like drinking blood? Or Is he just a weird serial killer that can't stick to his own M.O.? I feel like this whole part could have been deleted and it wouldn't have changed the story at all, instead it just made things more confusing when it comes to his character.
I've looked up the plot in detail on numerous websites but none of them mention this part of the story, they just skip over it.
If anyone has any better insight into this plot point I would greatly appreciate it because it's bugged me for years. I'd like some answers even if they're not canon and just what you think is going on. Thank you!
