Lara was taken aback by the woman's unearthly beauty as well as the fact she had a pair of she assumed were real vampire fangs.  This night was just getting weirder and weirder.  First the whole deal with the portal, the cultists, and now this.  What else could happen tonight?  She shook the thought off and listened to what this 'woman' had to say, having no past experience on how to deal with one of the truly undead as she apparently was.  If what she said was true, then maybe they didn't have to kill each other tonight.  Besides, she wasn't at her strongest anyway and her gun wasn't at its best, so it'd be a fool's errand to try to take her on now.  Even so, Lara wasn't about to let her guard down as she continued to aim at the vampire with her damaged gun, but she wasn't planning to fire now at least, not unless she gave the tomb raider a reason to do so.  "Alright.  Go on and collect your trinket, but I wouldn't advise making a return appearance, whoever or whatever you are."  She warned, letting the vampire go which was most likely a mistake but Lara couldn't just shoot her like a dog either, no matter what she might believe about her.  She hadn't actually DONE anything besides ransack their cart looking for something of hers, and that was easily rectified.  Even so, the sooner she was inside, the better she'd feel.  She had no idea how strong the vampire was and didn't feel like testing her luck in the dark, a vampire's natural habitat from what she remembered as a child growing up with the old fairy tales of monsters and magical lands and all the rest.  She'd have to ask her friends how they dealt with such fiends.
