I have always wondered why CJ never got Denise to meet Sweet, Kendle and Cesar? I mean it could have been cool if she appeared in the end of "End Of The Line", when Ken, Maccer, Kent Paul and Madd Dogg appeared, and he then introduced her to the others. I mean she lives few meters away from Grove Street. I mean she knew CJ and Sweet as she recognized CJ in "Burning Desire"
In my opinion, there is no reason to hide her from them, I mean why wouldn't they accept her? Imagine if Denise and Kendle became BFF's XD
