in the cd 2, when Tifa and Scarlet are " fighting", Tifa will hear: run untill the end of the canion... well....eho is talking to her???

:unsure:

i think it could be Aeris, and you guys? could you help me? sorry if there is a post about this :whistle:

I think that was Barret shouting from the Highwind

That's what I think, too. You can see Barret shouting when Tifa turns her head in that direction.
