I meaaaan if you wanna get technical, you said he came from after Endgame and post his depression and that could encompass a lot of things there when you think about it. After seeing the movie earlier today, I say that seeing as itβs a montage and the way itβs depicted in a past-tense manner, it totally counts as a flashback as events that took place before the movie! So, it definitely jives with your headcanon.
