Juno is more likely to be a fake. She couldn't possibly have survived that fall
Don't even bother mentioning being smashed through a glass/transparisteel wall. Irregardless, though, she didn't survive; she died and came back to life through the power of love. It's ridiculous, I know - I can stomach even Vader being captured by the rebellion, but that
moment is the one thing about the ending that truly pissed me off - but we can see very clearly from the situation that Vader had no time to switch the real Juno's corpse with a comatose clone of Juno that possessed all of the original's memories right up to the last twenty minutes of said original's life.
On another note, I have seen people elsewhere who despise TFU 2
's use of clonage yet simultaneously gush about the Thrawn Trilogy being the only
good series in the entire EU despite possessing much the same thing, and I can only shrug and move on.
