AH :
Well that's not the happy ending that I got on board with :/
There were a few. Apparently he doesn't save TSJ's life and since XY doesn't poison herself to death he also doesn't save XY a second time.
That would be quite different from the novel, where XY (and the reader) learns about it through a soldier yelling about it in a bar and then in more detail through Miao Pu 's report.
I don't care for either of those leaks, either. I'm pretty sure that XL's death will be different, in that the viewer will see it in all it's epic detail. It may be framed by someone giving a report, but we're going to see the fight.
I also think XY's Pearl of Tears will make an appearance there, which, wasn't in the novel, right?
If they were going to differ from the novel, I would hope that she could actually open the doll and see XY's message. He might not be happy with that ending, but it would give the viewers and XY some closure.
