Kristen and Fred and Caitlin - Ladon
Fred had chosen a costume specifically to work for two things. One, be a bad ass of a Halloween costume, and two, make it to where she wouldn't have to change for the haunted house; after all, Harley Quinn was a licensed therapist. After her time was done with Hydra, she left in search of Caitlin, and the obvious place to find a Ladon was at Ladon house; however, upon arriving her eyes found another person she enjoyed looking at, and she was wearing one hell of a sexy costume.
She moved through the crowd swiftly as only one with hunter training and vampire speed could, and came up behind the red haired girl. "Happy Birthday," she said remembering their conversation in the library where she disclosed that bit of information.
