Thor looks down at his hands as Tony begins to sing -- at the ring Tony had made for him. What had he done to deserve any of this? He had made so many mistakes, and yet still, Tony was willing to forgive them. He had once choked the man and yet he still didn't want him to go.

Even now, when he was responsible for the destruction of half the life in the universe -- when he was responsible for the death of his son and half of the people from their timeline who was here, Tony was sitting here, singing.

Why did Tony think he deserved this? Why? No matter how many times his mind went over it, he came up with nothing.

Thor doesn't say or do anything. He just listens to Tony's song.
