(I didnt actually die since I am the creator of these two but i faked it and that's when echo and I started arguing.)
Basically I watched and monitored echo as she grew until I called her one of my OCs. Basically. What I mean is that echo was a ordinary girl in a universe before I took her and re-molded her whole backstory to this tragic ending. So ye- and for the record I am not ok- :>
