The Echo could let you see something you've never known before without ever having experienced it firsthand.

but the Echo was used to see just slightly into the past only from what I can remember. I think this is nightmare not echo -- but I see why you are saying it now that I read the post you quoted

There's something else to the Echo you're all forgetting... you're already in contact with the person you're using the Echo on.
