She provides no value.
Begged Ghost to get back in the drug game instead of letting him fall back to the club - now she's dealing with the consequences and takes no responsibility
Overly emotional for no reason
The plot moves without her but somehow she's the victim in everything
Pretends to be a boss bytch but cant leave ghost and hides it under the disguise of "family" & Tariq dont really fukk wit her
I hear you on that, I thought she was bogus for convincing him to stay in the drug game and if I was Ghost I would have took Angie up on her offer of just picking up and leaving. Just starting a new life somewhere else or something like on some Frank Mathews shyt.
As for her being overly emotional however, she did just lose her daughter so I can understand that. Her wanting to stay with Ghost because of family and not wanting to leave due to their history together is also very realistic and why even domestic abuse victims stay. Even her being the victim in everything also makes sense because that's what happens when you're in the drug game in real life, if you go to jail your family suffers. Everything you do your family especially your wife suffers so her character is suppose to reflect that, him dragging her into all that mess because of his decisions and her wanting that life and power so she stays.
With that said I prefer Angela to her and if I was Ghost I would choose Angela over her cause she would be more supportive towards him turning his life around for the better. Tasha just wanted the money and the life and though she held him down and stepped up to the plate when she needed to for him, she did it more so to keep living the life she was living and not because she loved him. She even got it in with his Lawyer and his driver before that which is why I hater her character personally. I mean who she's is gonna fukk next? His tailor? His barber? the Mexican dude who does his yard work?
They both getting the pipe.
what does he suppose buy with that money that he don't have
