A celebration party was held at Avengers Base. Not only were the Avengers and the resurrected Guardians of the Galaxy there, but Doctor Strange and Wong from Kamar-Taj, as well as everyone from Wakanda, had also been invited to the banquet.
Before the banquet began, Yinsen had also brought Vision back to life—without even borrowing Doctor Strange's Time Stone. The Mind Stone had returned to Vision's forehead as well. He used it quite well, so there was no need to find a new keeper for it.
"Now this really is a perfect reunion!"
Everyone chatted away. Those who had vanished for five years spoke with familiar faces, trying to understand what had happened over the past few years, and they made a point of thanking the Avengers and Yinsen.
Of course, there were also plenty of people who wanted to witness the miraculous sight of two Tonys, while taking the opportunity to mock how much older this world's Tony was than his Parallel World counterpart—they already knew that the Tony from the Parallel World was not much younger than this world's Tony.
"Can't be helped. This guy learned a lot of things I don't understand."
Tony shrugged. He did not deny his other self's words, nor did he say anything like, "Actually, as long as this Tony wanted to, he could make a similar serum and restore his youth."
Though they were the same person, they were also not the same person. They had different pursuits, so there was no need to force his own ideas onto "another self."
While everyone else chatted and drank, Yinsen and Steve sat in a corner.
Steve wore an utterly disbelieving expression, staring wide-eyed at Yinsen.
"What did you say? Open up a separate Worldline just for me?"
"Opportunities like this don't come often.
