The eyes are kind of weird in this game, but it only seems to be the player character that they're weird with, it's like they have ADD and can't even look at the person they're talking to, but then they get better when they have their helmet on for some reason?
And sometimes the player character (female only?) occasionally has a slight grin about things they shouldn't be grinning about
And oftenly the eyes will be open so widely, that it's like the player is having Vietnam flashbacks
