Not so long ago, information about remote scenes of the film "Avengers: Final" appeared on the network, and it turned out that the audience at some point could see the conversation of Tony Stark with an adult version of his daughter Morgan. But as a result, it was decided to refuse from this plot stroke, and the directors explained for what reason they did.
Joe Russo planned to add the Tony and Morgan reunification scene immediately after activating the infinity gloves. The fact is that he has long wanted to understand how the soul stone affects a person. According to the directors, their idea was that during the use of this stone there is an opportunity to deal with internal contradictions and doubts. It was this scene that was shown in the "war of infinity," when Tanos, who killed by Karmory, met her child.
This moment of the film was incredibly strong, and the Rousse brothers were quite naturally decided to hold parallels between the relations of the Father and her daughter, showing the farewell of Tony with Morgan in the final. But in the end, during filming, the director came to understand that, since the audience had never seen an adult Morgan, which, by the way, was to play Catherine Langford ("13 reasons why"), it is unlikely to call them a big emotional response. And since the scene was not so powerful, as I wanted to leave it in the "final" did not make sense.
But at least the fans did not see the moment of the unity of Tony and adult Morgan, the scene of their farewell was still infinitely touching. And the fact that Stark, anticipating his death, wrote down a holographic message, once again proves how great his love for his daughter was.
