This scene amuses me.
They’re just playing a game. But after Eric taunts Kenny for being dead, Kenny throws a look his way.
It’s just a look. Just a glance. Just a sort of “really, dude?” and then he goes back to playing his game while Eric is utterly oblivious to Kenny’s reaction.
This scene is even better if you maintain the head canon (like I do) that Eric is the only person who remembers Kenny’s deaths, and so he knows damn well how his words would probably affect Kenny.
