I think that all of the children- which were probably all girls- in the Order's commune were chosen to be brought up for the ceremony. But of course, as we learned in the last video, most of them don't end up "right" for the ceremony. Which brings up the question, what happens to the leftovers? They can't possibly just be released into the world, since they have grown up in such controlled environments, and they're carrying so many secrets.
I think they get brought up to be agents for the Order. They are probably less informed than the other agents.
I think that's what happened to Gemma.
I also don't think Gemma's really "evil". I just think she was brought up to work for the Order, doesn't really know what the Order's purpose is, she's just doing what they tell her. Which would explain her hanging around Lucy.
Sooo yeah.
