Tony agrees to help

Steve exited the Avengers Compound and stared at the floor, deep in thought. He looks beat, the only possibility of victory now not an opportunity. He looks up as a deafening noise breaks the silence in the distance. As he looks, we see an Audi R8 speeding towards the entrance. The car pulls over to Cap, but goes a bit too far, then reverses to Cap. We see Tony Stark roll down the window and look at Cap.

"What are you doing here?" Ash questioned, with a surprised expression on his face.

"Why the long face?" Tony asked. Steve looked back at him. "Let me guess; he turned into a baby?"

"Among other things, yeah." Steve bent down a bit to glance at me through the open window. "What are you doing here?"

Tony ignored Ash and Steve's questions.

"It's the EPR paradox." Tony briefly explained and opened the door to get out of the car. "Instead of pushing Lang through time, you might've wound pushing time through Lang. It's tricky. Dangerous. Somebody should've cautioned you against it."

"You did." Steve said, picking up on what Tony was saying.

"Oh did I?" Tony tilted his head slightly. "Well, thank god I'm here."

"I'm guessing you came because you figured it out." Misty commented.

Tony held up his hand and on his fist rested a watch-type device held by a metal band.

"A fully functional Time-space GPS. I just want peace." Tony made a peace sign with his fingers.

"Turns out resentment is corrosive and I hate it."

"Me too." Steve agreed.

"We've got a shot at getting these stones, but I've gotta tell you my priorities." Tony continued. "Bring back what we lost; I hope, yes. Keep what I found; I have to. At all costs. And maybe not dying would be nice."

"That's how it should be." Ash nodded. Steve held his hand out for Tony to shake and he easily shook it.

Tony then reached back into his trunk to pull something out.

"Isn't that?" Ash questioned. Tony nodded before he hands it to Steve, who hesitates.

"Tony, I don't know."

"Why?" He asked. "He made it for you. Plus, honestly I have to get it out of the garage before Morgan takes it sledding."

Steve fits his arm into the shield.

"Thank you, Tony." He replied.

"Will you keep that a little quiet? I didn't bring one for the whole team." Tony asked as he turned to close the trunk. "We are getting the whole team, yeah?"

"We're working on it, right now." Steve nodded.
