He died in that cave, they just couldn’t let go.
When Pepper told him he could finally rest, it’s because they were ready to let him go.
No more pain, no more suffering, it was finally over.
He was back in the cave, weird thing in his chest, fear in his eyes.
He took and deep breath and smiled.
He wasn’t supposed to live this long anyway.He was born to die, he knew it since the beginning.
It was finally over, Anthony Stark was free.
He closed his eyes.
He could rest now.
