The Story of Tony Stark/Iron Man (Marvel Cinematic Universe)

Time Heist: Infiltrating Camp Lehigh

Scott and Tony met back up with Steve Rogers who had been successful in getting the Scepter. With only enough Pym Particles for a return journey home, Lang lectured the group that they'll won't be coming home. Suddenly getting an idea, Stark had an idea of getting more Pym Particles to take back the Tesseract, telling Rogers that it is in a military installation.

Stark told Rogers that he doesn't know the exact date but knows where to go but decided to go improvise on which date the Tesseract and Pym Particles were there. Stark begins to set up a date as April 7, 1970 before Rogers entrusted Lang to bring the Scepter to 2023. When Lang told them if they failed, there wouldn't be a way to come back home, Stark dismissed him and began to suit up, leading the pair to travel further back in time to the date that was settled and take the Tesseract that was in possession of S.H.I.E.L.D.

Arriving in 1970 of New Jersey, Steve and Tony infiltrated Camp Lehigh, where they discovered a doorway that is holding information in plain sight. Once Tony looked at the doorway closely, he examined the inner walls with his sunglasses, knowing that they could follow them around using the elevator. Stark and Rogers then took the elevator route while a S.H.I.E.L.D. worker looked over to them suspiciously.

Once Stark told Rogers good luck once he arrived on the floor that he tracked down, he managed to get inside a facility where the Tesseract had been held through his lenses and eventually found it near a vault. Stark then burned the ridges of the lock and began to capture the Tesseract and put in briefcase that he stole. However, in the attempt, Stark ran into the 1970 version of his father, who was looking for Arnim Zola. Once Howard started asking questions, Stark told him that he was a visitor from MIT, covering up his identity as "Howard Potts."

Despite Tony's success in stealing the Space Stone, Howard engaged his future son in conversation, leading them to take it by going outside. While Rogers worked to obtain more Pym Particles from the 1970 version of Hank Pym, Stark talked to his father about the flowers he was carrying, being noted that Howard's wife is expecting a gift from him after working so long and that a kid is coming along.

Once outside with his father, Tony was told that if Howard's baby would be called Almanzo, much to Tony's surprise and told to take his time. Howard asked his futre son if he was nervous when his kid was born, responding that he did in fact. As Howard followed up with further questions, Tony told his father that he just raised the kid as what he learned from his father, as they share their experiences with their childhood. Tony then when on talk about what he learned from his father, telling him that no amount money had bought a second of time.

As the both had reconcile each other's fatherhood, Tony noticed Rogers by the base and noted that he has the Tesseract locked up in a briefcase. With his father ready to leave, Stark told him that it was great meeting him before hugging, much to Howard's confusion. Stark clarified to thank for what he has done for his country and proceeded to leave the camp, finally getting to reconcile with his own father. With the tools to get back home, Stark and Rogers travel back to 2023.
