Lilly may be a normal human, but she had very little fear of anyone, which may or may not be a bad thing, when you see someone who hurt the ever loving FUCK out of your girlfriend when she flipped her lid and took off. So, as Lilly was hanging in Avarice (a rare thing, but it happened) and she saw Patience, she figured it was time for a little chat.
She walked straight up to Patience and gave her a slight grin/stare down. "Hey, not sure if we've ever really talked, but can we?" She was usually with Paige when they were out, so Patience had to at least realize who she was.
