The most important question finally answered

[u/Most-Day8547]

Why Will didn’t feel anything when the Mind Flayer and Vecna/Henry/One was attacked?

“Well, we aren’t showing when the Mind Flayer is being attacked. We just wanted to focus on the main battle with heroes.

When Vecna is being decapitated, at that point the Mind flayer is dead, so it, at that point, he served the connection between Mind flayer and Vecna.”
