Peter Is Heartbroken
Jumping off the last slide, Peter is obviously confused and hurt about all the Gamora stuff. He was in love, he lost that love, that love came back, but was not the same person. And, we know from the end of Avengers: Endgame, finding this Gamora was at the top of his mind. In fact, he was specifically looking for her at the end of the film before Thor interrupted. See above.
So though lots has happened between Gamora’s return in Endgame and her reemergence in Vol. 3, Peter is still heartbroken and confused about it all.
