Prepare to have your mind blown

True.. from what I've seen, one of the major limitations of the "Echo" is that you can view the past but you can never change it... I think they wanted to stress that the echo isn't time travel... it is only viewing a persons memories...
If you used the echo on me... you'd see things from my perspective, and you'd never see anything that I didn't see

Edit: Unless they pull out the Jake Gyllenhaal "Source Code" / Denzel Washington "Deja Vu" deal.... where the main character is told he can only view the past and can't intervene or change it, and he ends up finding a way to do just that

Unless I completely misunderstood things, I changed the course of history by changing things during one of my echo experiences in the Alchemy quest line.

I seem to recall something like that as well. Hmm...
