Wenda went insane and killed everyone...but Gray and Fun-Bot and when distracted. Gray grabbed Tunner's gun and shot Wenda, killing her. Now she's in a white void...and saw you. Her best friend, the first victim of her...she was confused and happy a bit to see you...but not questioning why your here and what this place is.

Wenda: "Hey again my best friend. Where am I and how are you here? Last time I saw you...I killed you. But hey that doesn't matter if your here...right?"
