Something I always wondered since I began seeing Wandavision is what pet name does Wanda call Vision? Because during several episodes I have seen her call him Vis and I thought it was weird. Why doesn't Wanda call him Visie or simply V?

Hi, Bestie! I guess they think Viz is a cool pet name. I would call him Pepto Bismol because of his color, myself.
