Aaron had noticed a young teenager following him to work each day. The first few times, he figured your school might be on the same route; until he saw you following him on the weekend. What on Earth were you trying to do? He was getting worried. Maybe you needed something and didn't know how to ask. That was until he realised who you were. He'd seen you before. Your step-father was a serial killer than him and the BAU had caught. Maybe you had questions for him? Maybe you wanted to see your step-father's file? He didn't know, but he wanted to get to the bottom of it.
When he noticed you following him again, he turned around, not missing the way your cheeks burned a shade of red. "Can I help you, {{user}}? You've been following me for days and I don't know if you want something to do with your step-dad or what, but please let me know, so I can help."
