Didn't play the game, but from what I've heard Orianna is shown as ambiguous in the game (i.e. such as children doing it out of their own will). Not sure if they worked the story through properly, or just tied it to the trailer post factum.
Uuuuuuhm.
Game facts:
- vampires do not
NEED to drink blood to live. They drink blood like a recreational drug. Not much unlike all that wine the humans are into in Touissant, in fact.
- the blood of children is particularly tasty. Young and fresh and unpolluted.
- you run into books in which vampires describe various methods of human husbandry. Keeping them in a natural environment apparently provides tastier blood and easier breeding than keeping them in cages.
- Orianna shelters orphans in that orphanage. This is of course better for them than starving on the streets. Or better than being held in cages.
- Orianna is genuinely shocked that one of the kids accidentally killed his sibling (they were hiding from a monster, and he had to put his hand over her mouth because she wouldn't keep quiet, and he accidentally apparently suffocated her.) Pretty sure a dairy farmer would be shocked if one of the cows killed another, too.
- Orianna sings a nice song to quiet down the kid and cuddles him as Geralt walks off to kill the monster who attacked the orphanage.
- A bit later, the kid is not in pain or fear as Orianna is feeding away on his jugular vein. Luckily, he's also not really into it though (
that would've been controversial...)
- Right after the interrupted blood exchange, as Geralt threatens Orianna, the kid steps between the two and begs for Orianna's life
Now... uhm... why would the kid do this?
a.) because he's totally donating blood on his own free will?
b.) because he's still in a hypnotic trance (maybe the song was part of inducing this trance)?
c.) could it be a situation like prostitution (exchange of safety and shelter and food for the entertainment and pleasure of a wealthy person), and he prefers safety and shelter over starving on the streets, and thus defends his ponce?
d.) maybe he's got some sort of Stockholm syndrome?
e.) it's like he's a well-domesticated cattle for that vampire. Well, actually, that's a mix of (b) and (c).
If it's like prostitution or cattle domestication, do you really think that a <10 year old has chosen this life style on his own free will?
