Wait...WAIT.
HOW DOES SHE KNOW HALF OF HER MEMORY IS MISSING. LIKE WHAT IF SHE WAS ONLY MISSING A THIRD OF HER MEMORY. OR SIXTY PERCENT OF IT. HOW DOES SHE KNOW???
And the whole "He looked like me, except the guy version." Nope nope nope nope. We don't know what she looks like, so how would we know what he looked like?
Play with character development a little bit, too. She's going a bit Sueish, but don't worry, Eden/Alex will probably grow out of it.
Please don't give her sixty thousand middle names. Nope. It's a Suemark.
