I know Rebekah. She helped us handle one of the vampires who stepped out of line and hurt someone, so that we didn't start a turf war. I don't trust her one hundred percent, but I don't think she'd be an immediate danger to your friend. If she considers Emily a friend, she might even keep her safe. She seems protective of the people she likes. I'd recommend keeping an eye out for anything that seems shady, and definitely using the vervain to make sure she can't be compelled, but I don't think it's necessary to stop her from hanging around Rebekah. Just, you know. It doesn't hurt to be careful.
Yeah. The world I come from is a dark one, it's practically drowning in monsters. A lot of people find that out the hard way, and sometimes, they join the fight against them. We've had good people watching our backs over the years, and a lot of them are here. Including the one cop I mentioned, and trust me, she wouldn't let anything happen to you. None of us would. And it's good that you're looking out for each other, too.
Hopefully there's something here for you that makes the time here worth it. It sounds ironic, but the monster problem in this city is pretty peaceful by comparison to home. I wish there were more we could do about reversing the crap that the wormhole pulls on people, though. Like returning you to your normal age, for instance.
