Question: Why did time not end when Thanos destroyed the stones, and what happens in now there aren't any? The Ancient One stated that the stones control the flow of time, and removing even one of these opens up the world to unimaginable horror. Well why did nothing happen after Thanos destroyed them all? And now that our timeline has no stones, how would Dr. Strange be able to stop Dormammu from coming back?
Question: Is 2014 now in danger or basically completely screwed? Quill would have woken up and probably have been caught by either Korath or Yondu as he had been knocked out. Even if he didn't, he would have gone to the broker with the orb, but this time there would be no Gamora outside to try and take it, he may have still been arrested with Groot and Rocket, however they wouldn't join them as they have no chance to bond over Gamora. Without the Guardians, Xandar would have probably fallen, but more horrible is Ego may have found Quill, and without the Guardians he wouldn't have been able to stop him so guess what...Ego destroys the universe.
Question: Did it actually have to be Tony that had to snap Thanos and his army? What difference would it have made if somebody like Clint or even Peter Quill snapped them? As long as Thanos and his army were destroyed the world was safe.
Question: How come Gamora had no idea that an infinity stone was in the orb in GotG but does in Endgame?
