Going back to end the of season one...

Spoiler for Hei's Sister:

Hei's Sister - what exactly happened to her? Did she die and give Hei her powers or is she inside the gate? Or do we not know and it was all left up in the air like so much other stuff in this series? lol.

I just watched the first season like a month ago but am still confused about that.
