CJ and Scratch

I tried multiple searches and I hope this theory hasn't been done if it has sorry.

I have a theory that CJ and Scratch know each other very well. I can't put forth any hard evidence it is just the way CJ seems guarded when ever the Mall faction is discussed.

The other thing that makes me think this is that CJ is an oddity. To be absolutely politcally incorrect she is a small in stature woman who was commanding and had the respect of Sean who Kalani thought was a big guy. How did she earn this respect? I think she has command presence which points to a former police officer. I think she might have dealt with Scratch professionally in the past and knows how dangerous she is.

Again no evidence just a feeling but if anybody can help prove or disprove I will read.
