Sometimes I think ME1 and ME2 Shepard aren't the same person, and the Lazarus project just created a new Shepard based on the original body.

This won't explain how I had my previous memories of course, so, perhaps, they are really the same person, or maybe the Lazarus project just did whatever they did with Grunt so he was born with memories of past battles.

It's something which is never really touched in the game. Most people react has news of my demise were greatly exagerated but, guys.. c'mon, ressurection is real!

Someone give Cerberus a Nobel or something.
