User blog comment:MimitheHedgehog:3/Plot holes + a theory for Silver's powers/@comment-3295259-20120816054705

i think it was explained that in the future mind powers were common

1-i guess they had a vision? i dunno if this was ever explained

2-i'd assume their spirits were "incapacitated" or something like that (most real explanation i can come up with is that the writes forgot about that)

3-the writers dun goof'd

4-oversight by the modelers

5-crappy programing.

6-the location of the Chaos emeralds is always shifting. (for example where did Elise get one at the beginning of Sonic 2006? but let's not talk about that...thing)

7-well we really don't even know why Crisis City even exists if it was erased from the timeline. i guess it somehow being restored also restored her memories?

8-Tails debuted in Sonic 2 so he was absent in Sonic 1 and thus never in green Hill zone. they jump into a portal to green hill zone most likely because it's the perfect representation of the past in the game and to save resources without needing to create another place
