Sin's voice line after defeating Act 8 last boss.

He starts talking about "the dark ember remains nested deep inside the putrid flesh of my dead beast" and so on (which I later found out is the "Dark Ember" voice line that he has in Act 9 Highgate), even though the text is "Sun and Moon return to their rightful places, leaving our path now clear." and so on.
