Not exactly the same, but... similar. Enough that Thor can relate, still absently rubbing at the join of his arm as he watches the burns on Prometheus' hand brighten to pink. "Yes. There was no warning... we fought to defend the others' escape, for as long as we could. Until I was... disarmed, and could no longer stand."

It's progress that he can even talk about it, and there's something sickly comforting about being able to share this secret that he's kept to himself since that awful day, knowing that his friend will not judge him harshly.

"I was restrained, and when he killed Heimdall, his sorcerer also silenced me. Loki... he traded the space stone for my life. And then Thanos killed him too. They left me for dead. No one else was found in the wreckage alive. Just me." He makes eye contact now, and reaches out to grasp his friend's shoulder, giving him a solid squeeze. "Until I returned, I didn't know if anyone else had survived." No matter how many times he thanks Prometheus for the part he played that day, it will never seem enough to truly express his gratitude.
