Cisco and Lustre
Of course Lustre had come to Finnick's party. He was one of her dearest friends from back home, and she wouldn't have missed it for the world. She also considered Chloe a friend, and given that she'd slept with both of them since arriving here, she was pretty sure that was returned.
It felt weird showing up without a gift, but what could she possibly give them? She was willing to help babysit and that sort of thing, but it wasn't like there was a store here where she could buy them a candle or something.
She'd just grabbed a drink and was waiting her turn to talk to Chloe and Finnick when she noticed a cute guy she hadn't seen before.
