Tony Stark: Quantum fluctuation messes with the Planck's scale, which then triggers the Doidge proposition. Can we agree on that? In layman's terms, it means, you are not coming home.
Scott Lang: I did.
Tony Stark: No, you accidentally survived. It's an billion-in-one cosmic fluke. Now you want to pull out... what you call it?
Scott Lang: A time heist.
Tony Stark: Yeah, a time heist. Of course. Why didn't I think of this before? Oh, because it's laughable, because it's pipe dream.
Tony Stark: The stones are in the past. We could go back, we could get them.
Natasha Romanoff: We can snap our own fingers. We can bring everybody back.
Tony Stark: Or screw up worse than he already has, right.
Steve Rogers: I don't believe we would.
Tony Stark: Got to say that sometimes you miss that giddy optimism. However, high hopes won't help, if there is no logical, tangible way for me to safely execute the said, time heist. I believe the most likely outcome would be our collective demise.
Scott Lang: Not if we strictly follow the rules of time travel. I mean, no talking to our past-selves, no betting on sporting events...
Tony Stark: I'm going to stop you right there, Scott. Are you seriously telling me that your plan to save the universe is based on, 'back to future?'
Scott Lang: No.
Tony Stark: Good, you got me worried there. because that would be horse shit. That's not how Quantum Physics works.
