So this option already exists! Its called "Confirm Ejects" and its in the settings in the dropship, if you have Confirm Ejects off it makes it so you don't know how many impostors are left or who is an impostor when they get ejected.
You know, what if he decided to quit Among Us for a while, maybe he was bored or he just had something else important to do, and he saw this post about Among Us 2 before he opened the Among Us 1 game. Or maybe he just never hosts rooms so he didn't know about any of the new settings for hosting rooms, because I host rooms very rarely, so I didn't know about this feature too (And I haven't played it for like two weeks, but I have watched some letsplays, and I first found out about this new "Confirm Ejects" only yesterday).
