Going with the 4d chess theme, who could be closer to Silent2 than Silent1? Valerie clearly has some messed up stuff going on in her head regarding who she thinks she is and who she wants to be. Wants to be seen as evil, but she also clearly cares about people (primarily MC) in her own weird way. Given the explicit double agent play she already made (helping MC against the Fraternity/Silent1 on the path to discovering her identify), it makes a strange sort of sense that she might be her own controlled opposition. Plus, having the role of the leader and the vigilante positions her well to control/remove actual dissenting factions (the professor, et al.).
Of course, no reason to think any of the above is more likely to be true than not, but definitely fun to try to read the tea leaves.
