But now the intro to Mass Effect 2 DOESN'T MAKE ANY ****ING SENSE, NONE AT ALL. I'm sooo pissed...
Fret not. There is still hope - mostly because I'm bored of studying Biology and was curious to see if I could provide an answer.
Solution the First: It doesn't matter from what altitude Shepard fell from - only that Shepard reached Terminal Velocity (~120 feet on Earth). Thus, it doesn't matter if he fell from 30 miles up or 300 feet up - they're energetically the same.
Q: Can the body survive terminal velocity impacts (if not necessarily still be alive)?
A: Yes. In fact, there have been several survivors in WWII that fell from over 30,000ft.
Solution the Second: Surviving re-entry depends on Shepard's armor. If the armor itself is capable of resisting tempratures near the 2600 Celsius range, then re-entry would not have destroyed any tissues save for where it failed - at joints and seals.
Q: Can Shepard's armor survive 2600 Celsius?
A: Probably. At that point in time, I'd assume every decent suit of armor had been tested for re-entry in case of an airlock failure. Shepard's armor can survive both the Occulus and Reaper Larva blasts - both of which are energy/heat based, and one of which (the Occulus) breached Normandy's loading bay. Since Normandy's loading bay is capable of withstanding re-entry, Shepard's suit should be able to as well.
Solution the Third: The brain isn't fully understood, so this is where most of the Sci-Fi happens. The structure of the brain is, so far, the best guess for individual identities. As memories get forgotten or are made anew, dendrites either reach out towards other neurons or recede. As long as Shepard's brain structure remained intact, there's a possibility that it could retain the same information - a possibility that could be reinforced with in-depth medical scans/examinations, since new memories (like being spaced) are held in different areas of the brain than older memories.
Q: Could Shepard still be "Shepard" after being spaced?
A: A decent chance. We know his head wasn't cooked thanks to the N7 Helmet, and the brain can survive terminal velocity impacts.
Solution the Fourth: The rest of Shepard could be reconstructed from DNA. Even though they show needles reviving dead blood cells (which I find far more implausible than surviving being spaced and freefall), as long as a complete genome could be found, they could physically reconstruct as much of Shepard as they needed to.
Q: Could the rest of him be reconstructed?
A: Yup.
So, there ya go. It wasn't a particularly long or in-depth thought experiment, but it does give some credence to Shepard 'surviving' instead of being utterly disintegrated or smashed into a pancake.
