Yeah, i'm mostly jesting here. If we keep getting more and more identity twists, the trick will run old and devoid of substance, but the plot has conditioned me to not trust that everyone is who they say they are.
I won't confirm or deny anything but we've already played the "character reveals their true name" card four times over the course of a handful of chapters. Doing it again with Robert would be overkill, if that isn't already the case. I've seen one survey response call the last act of 0.5 a soap opera and... well, they're not 100% wrong...
It also makes it hard for people to remember the characters if they all have multiple names.
