1. The sister got pregnant from a brother or another man?
2. Is she a twin sister?
3. Where did they get such property? And where does he work?
4. How old are they at Tangled Up 2?
5. Why does son hate mother so much?
All of this is answered in Tangled Up I, but I know how hard it is to get to the end. So I will do my best to answer them.
1. From what I saw the brother, but I never played through where the rich guy was able to successfully seduce the sister (i.e.- my relationship points were high enough to avoid that). However, there are people who say that if he does seduce her, it is actually his baby and not the brother's. Once again, I don't actually know if that is the case or not and personally have no interest in finding out.
2. If played with the incest patch from the first one, then yes, without it, due to Patreon censorship, no they are friends or roommates or some other contrived BS. No incest patch for this game yet, but I hope they do one, because for me personally, it's not the same without it.
3. Well, they get the house at the end of the first one and it looks like he took over for the mother at her office. I can tell you what happens to her, but I don't want to spoil the end for anyone who hasn't finished the first one yet. Who knows where the father is. He could be in prison or dead, hard to say, because he just gets thrown to the wayside.
4. I believe they were 18 or 19 in the first one. So, they are probably either 19 or 20, because they still have an infant baby in this game.
5. To be blunt, she is a bitch in every sense of the word. I think in my review of Tangled Up 1, I called her straight up cancer. Also, she tries to sabotage the relationship between the MC and his sister by trying to hook her up with some rich dude, essentially making the sister a clone of her. Don't get me wrong the MC is no saint, but compared to the mother, he might as well be.
