This is far beyond a longshot and I'm aware of that. but is it possible for zero to be immortui himself? And the person 'she' killed be meaning laxmus? I'm not sure this is as straightforward as we are making it seem. Maybe Erin is playing the long game by getting close with the enemy. I still am hard-core anti Layla to the point I'd root Erin over her (but I'm team Muka) so any glimmer of hope I can create I will do so. lol ...Cue the naysayers now:
And before anyone goes for the "look at all the bad things she's done" talk. I want to be clear that thus far there is no proof of Erin doing anything except hunt the vampires. which could be caused by any number of things, like them attacking her first or them killing someone important to her. we haven't exactly gotten much of her backstory, and there's got to be a reason for that.
