Jack has his grace and his soul AU, people are trying to kill Jack, slightly-overpowered-in-some-ways Jack, Avengers/Supernatural crossover, pre-Infinity War, I haven't seen Homecoming or any SPN past season 2 yet so this is going off clips and the interweb, Aunt May and MJ know Peter's secret

I need lots of comments on what I should change. Also, my stories always start out with lots of hyphens. And sometimes there'll be a period with a lot of ellipsis. 

"Jack-- get out of here. They want you dead and they're going to stop at nothing. Open a portal, anywhere, just-- save yourself."

"Dean! No, I can't-- I can't just leave you here."

"Yes, you can. Go. You have to get out of here. We'll be alright," Dean begged, even as he gasped for air.

"Dean's right," Castiel added as he bent over Dean and Sam. "They'll make it. But if you don't run, we both know they're going to be here soon. Open a portal and get out of here before it's too late."

Jack looked down at himself -- his jacket, the one the sheriff had given him when he was just a day old, had bloodstains on the sleeves, and his shirt was in tatters. Focusing, he pictured the shirt mending itself and the blood coming out. Opening his eyes, he turned his attention to a spot on the wall in front of him.

Behind him, Castiel told the brother's to close their eyes. A golden light washed over everything. Outside the abandoned warehouse, animals turned and ran. On the wall, a tear appeared, widening until it was large enough for someone the size of Sam. Jack glanced back at the fathers who raised him one last time... and stepped through.
