First off GUH. I freaking love Jennifer so excuse me while I sit in my corner and drool over her.
The only one of mine who would really know her let alone have any interactions with her is Xavier. He's probably spoken to her a few times at the Ministry as he tries to stay on semi good terms with all Ministry employees so this way none of them suspect him of being a DE or point fingers at him when shite goes down but aside from that he's fairly quiet at work. School is another thing, which I will get back to you on cause I need to nap for a bit before I face plant on my keyboard.
