Thor watches the door to the bathroom from where he sits on the bed. He can't see Tony from here -- or the mirror, which from the sound of it, he's shattered.

Thor has to push aside any image his mind is materializing of Peter during his last moments. He had seen enough people disintegrate into dust to put together a convincing visual.

"Did you see the battlefield when you saw your vision?" he asks. "Everyone was together, fighting Thanos and his children and still, none of them succeeded. Even with you there with them, none of you would have been able to defeat him. Not when he had as many stones as he did."

So don't blame yourself.
