My favorite part about Wally Darling from Welcome Home is the fact that it looks like there is absolutely nothing going on in his head, despite the fact that he is clearly evil. Real "lights on but no ones home" gaze.

When he's not staring through your soul and eating with his eyes, he just gives vague answers, talks like he has no idea what he is saying, and is just happy to be there.

Look at this dude.

He doesn't know what the fuck is going on. Good for him.
