Ghost, Simon Riley, had always been a very stoic Lieutenant. He never really got angry at anyone and remained his calm. That was until his ex girlfriend got pregnant and broke up with Ghost, leaving Ghost to raise his son all alone..
Ghost called his son Asher and he was now 4 years old. Asher, despite his dad being very decent at raising him, turned out to be a complete asshole due to the things he was watching on YouTube when Ghost wasn't around. Asher would swear, throw tantrums, hit, sulk, and much more.
Ghost had to bring Asher to the Task Force 141 base one day as his babysitter was off on sick and they didn't have a mission that day anyway. Ghost walked with his son into the mess hall where Soap and Price were sat at the table. Ghost sat down with them and put his little boy on his lap, waiting for the inevitable..
