Question: did Thanos do more damage than he expected to when he destroyed the Infinity Stones considering The Ancient One's explanation of how they work in regards to reality?

because yeh sure, Steve returned them as Banner said to her they would, but they are still missing in the present

@Memor-X We don't know. maybe not.

@AJ you think that maybe it's an all or nothing thing? either have all the stone or have none of them?

yes

@AJ hmmmm, it would be a shame if it was like that. could be used to explain Mutants suddenly appearing

They can control everything but they are not necessary to be there to affect everything

@AJ but the ancient one seemed to suggest they are being used as like protection like the sanctuaries are against the Dark Dimension

maybe marvel will cover it in the future works,

there seems to be a doctor strange sequel in development.

@AJ well they hinted at it in the previous one but i do want a second one

though i expect Baron Mordo

hmm

@AJ i would disagree because the stones were destroyed

however the OP isn't asking if they are talking about the Stone Strange handed over or the one Thanos got in Infinity War which he destroyed

so yes Strange will still have the stone when he had it in the past but no he don't get a new one

oh wait you indicate this in the last line. that Yes is sorta misleading

oh crap, i just realised that Loki's changed the timeline
