This is just basically a story of after Aaron Hotchner left the BAU that ive came up with. Im also going to let you know this is a dyslexic who has never wrote a story in their life asides from primary school... so any gramatic errors im sorry lmao... anyways here a brief:
After leaving wittness protection, Aaron finds himself choosing over a job or keeping him and his son safe, he grabs his phone, reluctently makes a phone call to say he has decided to leave. Jack is more important and Aaron would rather give him a great life instead of worrying that he may be in danger, he may of have had Haley in his mind making the decision, because after what happened with Foyet, he doesnt want to lose another person he loved whilst working a case. Making this desision was never the easiest and Aaron would have never have thought of the day where he would have to leave on such short notice, part of him was thinking about changing his mind however he knew the BAU would understand his choice with no judgement involved, so he hopes anyways.
