Where plenty of mortals knew about the immortal world (her brother included), Norah was completely ignorant. When she saw someone behaving oddly she just thought it was human nature and moved on. Sometimes it was just that, other times it was an immortal being themselves. Norah perked up a little, "Oh! I'm Lachlan's sister, Norah." He probably would have introduced her as his baby sister. She offered a hand in greeting. She hen shrugged and motioned to the door, "They're out doing whatever it is they do. They're bound to come round eventually. I just wanted to drop by and see my brother."
