It was never stated but kudos to them creating all sort of fake facts or arguments and twisting words to make her look good.
Apparently we should believe Bella when she says Elaine was a really nice and caring person before meeting dickface BUT we should not believe when she says elaine threw all his things out. We should also believe elaine version of what happened all those years BUT not believe the mc version(he confirmed she was a bitch right at the start of the game). Indeed we should believe everything she says as the ultimate truth.
Well my twelve was also a shot in the dark, but Dad did get MC reasonably soon after his mom died and he was not much more as max an early teen when that happened, based on some things said with Monica at carnival I even assumed slightly younger. That might be bad memory from my side though.
Also I might misremember but Elaine was either already in a relationship with dad when mom died or pretty soon after. She was around at the time of the Monica allegations the way she spoke of it not something she heard 5 years after and had a long relationship with the dad. Also with current age of MC it would not fit he was 16-18 when Elaine came into his life.
Like I said I am willing to believe that Elaine has reevaluated her life and some of her actions especially considering MC after reading the will. There are some hints for that if you take what fortune teller said as literal truth and a few more things, though there is also still not enough communication and trust between MC-Elaine. They are still rebuilding that and her behavior directly after dad died does not help with that, whether Bella told the truth bout his stuff or not. Now we do not know if someone egged her on.
It is also not impossible that Elaine is fully playing MC though and she is still a bitch for whatever reason and just playing Mc to fulfill her condition and did not convert after reading her conditions. Without knowing those conditions we also can not know whether the hints she gave about them to MC are false or not.
Now Bella and what Bella has said. Either we believe as some have interestingly made a case for that Bella may well be the number one suspect to be Dizzy and then we can not believe anything she says also not in defence or attack on Elaine, since she is working to get the whole inheritance and doing whatever it takes. Interesting enough that also means she should keep MC in contact with Monica and family. I can not really remember either Bella or Elaine doing that, besides Bella possibly bringing his stuff over nd we know Dizzy knows his condition.

(Now I am somewhat suspicious maybe too many trails lead to Bella and she is a bit too obvious and do keep a few other options open for now, one that would really surprise and disappoint me and as such would make sense if devs want to be mean

)
Now if Bella would be Dizzy and as I suspect that Elaine, though she has no proof, might have a strong suspicion who Dizzy is, well that could lead to some interesting fireworks and drama, whether Elaine cares for MC or not and is only cucked by her younger sister.
