I understand the pivotal part it plays to Loki's psyche to see infinite stones, multiple copies no less, just sitting in a drawer like paper weights. But why are there so many copies? Is it because they have been pulled out of the timeline at various points over and over again to restore the timeline? For my daughter and I, the impact of seeing infinity stones just sitting there like candy wrappers definitely hit home. The impact and realization was like a ton of bricks hitting the deck. Probably the biggest "wow" moment for us through all 3 series so far. Powerfully, masterfully done. I get the significance of it, just not the how of it.
