What is required the most I think in a future update is for Ashley some how to cause a major beat down on those Mexicans. I think there may be more than 1 way that this can be approached, and various characters could be of use in going about helping her.
Jasmin: She is a very buff t-girl. She knows all abut the body as a masseuse, and a little known fact about people with such knowledge is they know a whole lot of pressure points which makes them often times gifted in the martial arts when they take that up as well. Seeing as she is trans a lot of trans people are victims of hate crimes so there is a good chance she picked up on some fighting skills. A scene could go down where Jasmin, and Ashley are out at say the park, or a club, run across Wilson and his fuckboy friend. Jasmin beats the ever loving fuck out of them for disrespecting Ashley. Possible shit that could also go down is Jasmin anally raping them, or making them anally rape each other.
Jack, and Tyrone... I think these 2 meatheads would give a major beat down to the dirty Mexicans. It could go down somewhat in the fashion of Jack, Tyrone, Isis, and Ashley have a meet up at a bar, or club. Once again the dirty Mexicans try to pull some shit like when Ash, and Eva were out with there boyfriends. Jessica would probably be there, and encourage them to beat the fuck out of the Mexicans as she knows what they did to Dave. Jack, and Tyrone two big buff alpha males don't take that shit one bit, and stomp the fuck out of them. They are probably also rivals in some drug dealings so are natural enemies... Unless of course they share a supplier, and are all friends in which case things could get ugly for the girls.
Eric's Dad... Ya, he is middle aged, and ya he is a bit overweight and out of shape. Don't underestimate this guy though as he looks like he could throw down, and he seems crafty. I could see him cracking some Mexican skulls with a tire iron, or running them over in his car.
Doug... Young airhead jock wrapped around Ashleys little finger... I get the feeling if she pointed her finger at Wilson, and said "beat him up for me" he would obey, and fuck some shit up.
Dave, Eric, and Eva. I don't see things going down like the first time in the club if these 6 ever cross paths together again. Dave got all sorts of fucked up by them, and Eric got a black eye so they are going to want revenge.
Police route... There has to be some sort of police route for these guys. You already have the option to call the cops on them. Would love to see these Mexicans shot by police, or deported, or sent to prison.
