Through all of those scenerios, the problem is why did Yamamoto let go of her and let her drift?
All in all, it would be much easier to break into her office and get the REAL BC and/or get DNA to prove his REAL parents than go to all the trouble of faking a death. Aside from the one lie about the BC, which the entire world knows she lied, she wasn’t that much of a key figure.
