she was recruited in july 2018! so peeping his bio i think that could work, since he was a handler by that point? essentially the reason she got so attached was because she feels fairly indebted to him, as the program she was in before she was recruited by aegis was dismantled and nearly everyone involved was terminated, so by swooping in and recruiting her he literally saved her from just being casually murdered, if that sounds like something you'd be interested in!
