(Thor's surprised, mostly because the Chitauri incident was years ago (for him!) and he didn't realize it still hung over his friend. But humans are fragile and short-lived. Thor's gone through a century not even counting the years before, they don't have that ability. He isn't going to discount pain, especially not done by his own brother.

He feels the anxiety and Tony's distraught, moving his arm around Tony's shoulders so he can give that full protective support again. So Tony can feel held and safe. Thor kisses his cheek sweetly, nuzzling his ear.)

Come back to me. Come back to here, now.

(His voice is soft and intentionally close to Tony's ear to try and ground him in the now.)

Perhaps it is difficult for you to see the next part because you were unconscious. I can tell you what happened on the ground, maybe you can try to picture it, to fill in the memory.

(Thor leans back to look at him again.)

We saw you fall from the sky as the portal closed and realized you were not slowing down. I started to swing Mjolnir so I could go fly and catch you, but the Hulk got there first. He caught you safely and brought you down where we all gathered.

(He remembers the moment well, how certain he was that he was dead. A tragedy, he did not know him well then, but he knew he was a good man.)

Hulk howled at you and you woke up. You were caught, my dearest Tony. If you cannot picture the Hulk saving you, picture it being me.
