I'm glad that Hoshi still remembers Traitor plot.
And I know that you guys thinks that it is really bad choice, while I believe that Tori suits for this role more then anyone. Let me explane:
1. Tori was living with heroes for s long time, so if she was all this time traitor made her character really complicated, case she didn't give up of beign evil;
2. The fact that she was able became not invisible maybe talking about her connection to AFO, case possibly he was the one who give her invisible quirk;
3. She was ally of Shigaraki, and part of AFO team from the very begining of series;
So in the end I believe she could be blood related to AFO, or related to Shigaraki. Maybe she will became owner of AFO power in the end.
