I hate to be that guy and open up this can of worms again so I will advise BD not to click on the ispoilers but the patreon poll specified age, race and background with the result being that the third client should be a middle-eastern princess in her mid-thirties looking to come to America in search of a new life. Somehow, BD managed to turn that into a manic pixie dream girl with severe arrested development who had been in hiding for 20 years and thought of Rachel as her mother. That may be consistent with the poll but is certainly not in the spirit of it which is why, at the time, Tali recieved a lot of negative feedback.
The real kicker is that she isn't a client in the same way as Anna and the other two whose names I always forget, she's Rachel's 'daughter' who is effectively being pimped out. I may be a sex positive member of the LGBT community but I have a real problem with the denial of consent and, by setting up her 'daughter' to be impregnated by our MC, BD has crossed a line that I find unforgiveable and I truly hope he fixes it.
