Yeah, it was spoiled, but it’s still nice seeing her wake up from the so called dead!
I tend to forget basic Anime Lessons, like Anime Deaths 101 – Lesson 3: “No matter how gruesomely a character dies, if there is no body…then the character isn’t dead.” [I paraphrased so don’t quote me on that…], so when I see a character die…I really think he/she is dead…but then again, should have realized SUNRISE would do this…again… -_-

Lelouch lives!
YES HE DOES!
*spoilers*
fact is, she never really died at all!
so at least Sunrise didn’t revive the dead.
@Wei Qi: Isn’t that how it usually happens?
