Delilah spotted someone in the hallway; A boy, he looked lanky enough. She approached him, her shadow looming over the boy as she watched him toss a ball into the air and catch it while he read in the hall. 
"Hey buddy~" She cooed, even though she wasn't very well acquainted with him herself. It was clear to see that Delilah wasn't here to have a pleasant conversation, she probably didn't want to have a conversation at all. Her behavior was slightly menacing, though this was Delilah's way of 'introducing herself'.
