One could draw the parallel between Anduin's attitude towards the interrogations and Arthas' attitude towards the Culling of Stratholme. We also know that Anduin remains in the Maw after the other faction leaders were rescued, and we have a datamined repaired Helm of Domination. Assuming Terenas Menethil was correct when he said there must always be a Lich King, could it end up being Anduin making the sacrifice play for the good of Azeroth?
The safe assumption is that Bolvar will resume his duties, and a farfetched option would be Arthas somehow reclaiming the Frozen Throne. But what if the third (and admittedly even more farfetched option) is Anduin taking the helm and infusing it with the Light? We have a lightforged undead, and Bolvar himself turned the crystal in the helm orange with dragon fire when he first donned it. We also have an example of Anduin infusing Shalamayne with the Light rather than the red rage color when Varian held it. I admit it's a VERY big stretch, just curious if anyone else has thought of it.
